Razer Atheris Ambidextrous Wireless Mouse: 7200 DPI Optical Sensor - 350 Hr Battery Life - USB Wireless Receiver & Bluetooth Connection - Classic Black

This may be the best travel mouse I have ever used. Heavy, solid, pairs easily and never drops connection with either the wifi or BT. Its weight is primarily affected by the 2 AA batteries carried internally. Some opinions on weight: If you game or do basic office work, you will never be more accurate than with a heavy mouse than with a light one. Why? It simply gives your brain a starting point and allows you to calculate an exact end point because you have a known weight with which you are moving allowing you to end up in the exact location that you intend to be at the final destination. Headshots are much easier with such a tool. There is one advantage with a light mouse however in that you will move much more quickly from the start but you will trade accuracy as a result for that twitch factor, so take your pick. Lets just say you will never be accused of cheating if you use a light mouse because your movements will be more erratic and far less accurate. In addition, if you game with a light mouse, expect to hate the transition to a heavy mouse for a while until you get used to it. Only when you start seeing some of the incredible shots you pull off will you start to appreciate it. Pros: -Heavy; -Solid construction; -Smooth accurate glide surface; -Easy to pair with solid non-dropping connections; -Works equally well on Linux as it does on Windows without hunting for drivers. -Includes both wireless and BT so it works on anything; -Very comfortable fit for a small mouse. Cons: -You will hate this mouse if you have big hands so dont buy it; -You wont like it if you prefer a light mouse; -Razer software wants to link to a real person / email address before you can use it. I have not tried to load it yet so I dont know if the current version is still doing that but it is almost a guarantee; -Marketing preys on Consumers who dont understand DPI and I hate that about mice manufacturers as they all do it these days. I better elaborate on the last one. DPI on this mouse is an astronomical 7200 DPI (note this is not the industry highest either). What does that mean exactly? Well, it stands for Dots Per Inch. To put that into perspective on why you really dont need it, you might first want to understand that mice that were 600 DPI back in the 90s and 2000s and they still work perfectly fine and were like that for years. That is all you could ever buy until Razer changed that game with a product called the Boomslang mouse. Matter of fact, I think I still have a Boomslang around here somewhere, but this is off subject and you can probably read that history yourself. To make this easy, DPI of 7200 means in exactly 1 inch of travel, your mouse has the resolution to move 7200 dots worth of travel. This is simple enough. Now lets analyze your monitor. The majority of monitors are still 1080p which means you have 1920 dots across. If you do a literal translation of this mouse to your desktop screen at 7200 DPI, that means your mouse would traverse from left to right of your entire screen 3.75x is the space of 1 inch. If we were moving vertically, you would traverse the entire screen 6.67x!!! Even if you have a modern 4K monitor, 1 inch of travel would mean you would still be traversing the monitor nearly 2 times! If you are starting to visualize this, this mouse would be pretty much unusable if it were not dampened by software and no longer running at its native resolution. When razer released its Boomslang way back when, if you didnt dampen its 2,000 DPI, it was already unusable right out of the box. These days, it seems to be expected that manufacturers are doing this and Windows will dampen it right out of the box for you. Lets just say while your mouse may be 7200 DPI capable, you are not really using that capability. The point of all this is simple... Marketing hype for these super high resolutions is just that, hype. You are not going to be a better gamer if this thing was 2,000 DPI or 20,000 DPI. You cannot possibly use these resolutions effectively. With that said, the way the mouse feels and moves physically means everything and that is what will win the day, and boy does this mouse feel right when moving it. I hope all this makes sense. What I have not tried: I have not loaded the Razer software which allows you to tweak the mouse like polling rate and DPI. I might load it to check out what the latest tools looks like but there is no need to load anything special to make this mouse work and I likely wont use the tools after the initial look. Update 1/19/19: Mouse has a major con.... My wife liked it so much she took it. Just had to buy another one to replace it. In the approximately year I have owned it, I have never had a single disconnect / dropped signal as mentioned here by other reviewers. My only thought is that there is a problem with the bluetooth on their laptop, a problem with drivers on their laptop, the mouse entered some sort of sleep state which it will do after a certain amount of inactivity, or they got a bad mouse. Note that I have never used the official Razer drivers either so it could be a problem with Rzer software that I am not aware of.

This mouse is small, I bought it to travel with and its great until you use the bluetooth. I tried with two different devices on bluetooth, and it sucks on both. It works great on 2.4ghz, but I dont want to use it on that because I need my USB ports for other stuff, and dont want to have to use a SUB hub either. Via bluetooth, there is a huge delay between the time that you start moving the mouse and when the mouse moves. It can be a little frustrating to buy a bluetooth mouse, and then find out you have to use it on 2.4ghz.... Kinda annoyed because otherwise it is a great travel mouse!

Came in perfectly sealed with all the parts included. The mouse feels weighted for how small it is which helps keep the mouse easily planted to the mouse pad but not to heavy as to make it annoying. Feels high quality with good responsiveness to boot plus bluetooth if you need it. Yes the DPI is adjustable through razer synapse.

The mouse is much smaller than I expected. I have large hands and its a little uncomfortable to use. So thats not a terrible thing, unless you are large featured like me. Otherwise its a great mouse, no complaints.

2.4 GHz adapter works amazing. Great response, a smidge touchy for regular everyday stuff. Bluetooth is just ok. Had some issues with signal issues to my HP zenbook but need to test with other devices. Feels great and awesome battery life. Good portable everyday mouse.

I like the size of this mouse and that it can connect via BT or Dongle/2.4. A long time ago, I bought the Razer Orochi. What a POS. The plastic pads on the bottom were not recessed and would fall off after a couple months. That mouse was over $100USD at the time. The pads on the bottom of this one are recessed. Note: In order to connect without the dongle, you need to have a newer BT module. One that supports LE. My older MBP does not have this. At first I thought there was something wrong with the mouse. It would not pair. Then I went to the manufactures site and that is where I found LE was required for BT connectivity. The packaging was nice and the manual. It also came with some stickers.

UPDATE: Jul 8 2020 Changing back to 5 stars from 4, I did try the previous mouse with brand new batteries and seems ok. Hard to tell what happened, will keep using and see if the issue still happens. UPDATE: Jun 21 2020 I still think that the mouse is fantastic and way beyond excellent than MX Anywhere 2s. I will have to echo what a 2-star review said: Only lasted three months. It worked perfectly until I hit the 3-month mark. At that point it just died. Stopped tracking. Changed the batteries twice. Now, it just randomly stops. Ill pull the batteries out, put them back in, unplug the receiver, plug it back in. It will work fine for about 15 minutes and then freeze. Lather, rinse, rep That is exactly what is happening to me, bought another one brand new and everything seems fine, if use the older one bought few months ago it would work for about 15 - 20 min and then stops moving on the screen, then reconnects again, etc SUPER SUPER frustrating. Thinking that an OS update went horribly wrong and messed up the drivers had to reinstall the OS and tools to find out that issues was still there. This is when I purchased the second mouse and all is well now. This means I have hopefully a few months before it goes dead. This is an extremely well tracking mouse and ergonomically perfect, I even dropped the use of high perming Logitech G305 in favor of this one. Hopefully razed keeps this formula exactly as is just workout the bugs. Im ok paying higher price if this is rock solid reliability like the logitech is. Removed 1 star for this to bring attention, other than that this is an extremely top notch mouse - when it works. Sadness creeps in to see this model die because of not listening to customers. ORIGINAL: Feb 4, 2020: FANTASTIC ! Way better than the Logitech MX Anywhere 2S both in precision, DPI adjustments and feel better in hand as well but that can be a subjective thing. The critical tech wise is it miles better than the 2S, precision, DPI adjustments accross platforms and OSes. For logitech there is some software to be installed to barely tune the DPI - which requires mac or windows.

Love this mouse. Love the feel, battery life, and performance. Dont listen to the 1-star reviews on here. As far as I can tell this was only from the bluetooth feature being wonky. Ive had mine for 2 years and never needed to use the bluetooth feature once. Im not even sure why you would need it as the 2.4 works perfectly and barely drains the battery. I believe the bluetooth adds an extra feature of being able to use it on a phone that doesnt have a usb port. This is a handy feature but certainly not a necessity. Amazing mouse. If mine ever breaks (probably not for a long time) Ill happily buy another.

This mouse is pretty nice for what it is and at what the price its at. Ive found that the mouse is a bit on the small side for my hand but it gets the job done. Its best to plug this into a USB 3.0 port as I have found some problems with using it through a USB 2 port. Customization with Synapse is pretty nice and gives me the option to remap any of the buttons on the mouse.

It works but not as advertised. The 1000hz polling rate only applies if you use the dongle. If you connect via bluetooth, you do not have the option of polling higher than 250hz. Bluetooth was the entire reason I got this thing though. So if I have to use wifi anyway, I may as well get a better mouse. Its not awful. But the batteries are not rechargeable. It only has 5 buttons total. And it is really small. If you have big hands, using this mouse will be a problem. I have average sized hands (well...for my size...Im 62) and for me, this feels really (uncomfortably) tiny. Like, even doing work with it ia awkward...gaming on it would be even more so. If all you want is a basic mouse that is portable and has bluetooth capability, this is probably fine. But $50 seems a little steep for a basic mouse like this. There is really nothing that special about it. No LED lighting, limited buttons, no high polling rate. I ended up returning it. EDIT - I removed the part about Wifi drops. Apparently this is an issue with all bluetooth mice. You can solve it by connecting to wifi at 5ghz (Bluetooth uses part of the 2.4ghz spectrum), and also changing laptop Bluetooth power settings so that they are on preformance all the time (many laptops are configured to try to save power on Bluetooth, but you can override it in settings).
