Review on Iverntech 400Mm MGN12 Linear Rail Guide With 2 Black Stainless Steel MGN12H Carriage Blocks For CNC Parts And 3D Printer Upgrades by Jason Hymon

I've always read about how expensive good linear rails are, but for how cheap these are and how decent the reviews are, I decided to try them out. I was tires of all the slop and constant adjustments on my Ender 3 Pro so I put these in the X and Y axis. It's been one of the best upgrades I have done on my printer so far.I bought replacement bearings for these like a few other reviews mentioned, but I haven't even bothered taking them out of the packaging yet because these work well enough for me in their stock form. I would definitely buy them again.
