> 24 hourFor the money, its great. Uploading and running a program is very easy. Needs a breadboard and power supply/data cable. So much info online for this superior Arduino family device.

> 24 hour1 out of the 3 was nonfunctional. The first one I tried to load some test code to could not be seen by the computer. The other 2 worked just fine for running Wled but one could not be seen written too when using identical code to the other two. Ended up returning them.

> 24 hourI followed all the directions on the web site about installing the arduino IDE and configuring it for this board. All of that seemed to go well and the arduino IDE was running ok. When I went to upload my example sketch, no matter what I tried, I got an esptool.FatalError: Timed out waiting for packet header. I read on the Internet that you could hold down buttons to alleviate this problem, but no button combinations helped. I have now spent several hours fighting with this and as a matter of self respect, I am unwilling to invest more of my precious time messing with this.

> 24 hourI just received this item and within 15 minutes I had it connected to the Blynk server where I am able to display and record the temperature and humidity of my reptile habitat. This is my very first NodeMCU device however the feedback from other purchasers pointed me in the proper direction for setting it up through the Arduino IDE with which I am familiar and comfortable. I am very pleased with the cost effective nature and overall ease of use of this product and will be buying many more of them for future projects and development ideas. Highly Recommended! If you are a newby to the ESP-12E family of wifi enabled microcontrollers I would suggest checking out Instructables or GitHub as a resource to get you off the ground and flying with IOT genre projects. Its utterly amazing what can be performed with such an affordable and tiny controller. Your imagination is the only limit!! 5 Stars!

> 24 hourSure I am may not be the sexiest dude in the bunch, but dont push me to the edge. I will node you for a long time. And get this, this little guy does have access to DFDS.478.PAA which is a super bonus.(please work on your table manners)

> 24 hourOverall, this is a great device. Having wifi and a bunch of ready-to-use digital IO is great. The supplied examples were also very helpful. My complaint is that I have repeated problems with uploads failing from the Arduino IDE. When this happens, I usually have to unplug the USB cable and plug it in again to get uploads to work. It really slows things down.
