Presicion para ender 3v2
Lo usé en mi Ender 3v2 que tiene doble motor en eje Z y la modificación de 350mm de altura en Z, FUNCIONA PERFECTO Estoy satisfecho Nota: aplique grasa de litio en todo el tornillo antes de instalarlo, por gusto propio, no sé si es necesario pero a todos los ejes se lo aplico y me va bien

These are very high quality and very well packaged.
I bought these for my custom Ender extender for a 550 build height and they are literally the exact same as what comes on the Ender 3 Pro and V2 just really long. The original Ender extender was not tall enough for me so I decided to go with this and the 600 mm 2040 V slots and I couldn't be more happy with it as you can see in the picture how much taller and wider this is than my S1 to the left and V2 on the right

Good Value
The screw are very good for the price, given where i live(right on the beach) corrosion is a real issue and these screw are showing no sign of the salt air affecting them. The brass nut leaves a lot to be desired though, they work but you will have to couple two of them to get rid of backlash and slop that they have.

Lowrider V3 CNC Build
I am building a Lowrider V3 CNC from V1 Engineering and these form part of that build. I have done the 3D printing part of the build and gathering all of the necessary parts. Whilst I haven't put everything together yet, after my initial research and inspection of these, I am very happy. I will update the review once I have completed the build.
