Bought the CR Touch over the BL because of the metal probe. Installs easily and works great.
These auto bed leveling devices when calibrated in the software correctly work excellent.
It seems to work fine, but after the firmware update to use it, I am having a tough time getting the Z-axis offset correct, but that is more likely a use issues than hardware.
iv recently gotten into 3d printing and absolutely love this made the process so easy and super simple to install took me less than 10 min from power down to power on
I really cannot add more. It works as advertised and has fixed my adhesion issues with the Ender 3 Max
