> 24 hourThis a solid unit already assembled ready to go! this took less than 10 minutes to install. Would have been faster but I took my time to get the correct tension with the knob. So easy ( Just 2 included hex screws NOT phillips yayy and 2 tension nuts) I am going right now to purchase 2 more for my other two Ender3 Pros. Thanks UniTak3D for a Great product and super fast Amazon shipping!

> 24 hourWorks great!!!! I had one I printed and it worked but this is so much more fitting for the printer style....strong and slim!!! I love this x axis belt tightener!!! Went on easier than the printed one and is super solid Perfect upgrade for an ender 3

> 24 hourThis works great on my CR10s and should be a 5 star product but wrong size bolts were provided. I had enough spare shorter bolts that I was able to quickly and easily install it. I bought the x-axis tensioner along with this item and that installed quickly easily, no need for additional hardware/parts.

> 24 hourWorks very well. Easy to install and super durable. Should be the gold standard for 3d printers to have pre-installed.

> 24 hourThis has made getting the belt on my Ender 3 super easy and fast. For my ender 3 I did not have to re use any of the standard hardware which many people said they had to. I did not and I did not have to take the belt off to install this... I did have to take apart the entire part but it is straight forward and easy to understand.

> 24 hourThe toothed idlers wheels wobbled from the time it was opened. Everything else about this tensioner would be great if the idler was good.

> 24 hourGreat fit and easy install on my CR10 Max. This tensioner is a must for all Creality 3d printers.

> 24 hourGreat tensioner, well built. As someone mentioned, if your bed size is set to 235mm, the Y carriage will hit the tensioner, not a problem for me since I upgraded to linear rails.

> 24 hourI have a Ender 3 Pro and the bed carriage crashes into this tensioner. <--READ UPDATE! UPDATE 9/28/21 : If you use Bigtreetechs firmware for the SKR Mini/TFT35 they change the default bed size to 235x235 instead of the default 220x220 and this will cause the pom wheels on the Y axis to hit this tensioner. To fix this change it back to 220x220!
