Fits perfectly in my ender 3 pro. Would recommend this product to any one how has ender 3 it is easy to install, works great, and keeps the heat were it need to be.

Allows for steady nozzle temperatures.

Work as advertised

I am not sure if I got a defective set but it did not fit very well (had to trim it a bit to put it on my printer). Also, did not even last a month :(

I think these are a good idea and helps work several issue, these for average but I installed the without removing anything so it wasnt as easy going as it could have been.

Great deal for 3

works

Good to have a few of these around for when the original wears out

Perfect fit cr10s
