Working good so far, on my Y carriage on a 12x8" i3 (with an aftermarket aluminum carriage) Just in case anyone was wondering the holes on these are threaded for short M4 bolts.
I had to use a rotary tool to cut bigger cutouts in my Acrylic frame to accommodate the bigger bearings, but it only took a few minutes and its worth eliminating zip-tie bearings!
Update: All four bearing modules used on my prusa i3 are still functioning flawlessly. There's probably 300+ hours on these bearings and I don't believe they'll be failing anytime soon. But once they do I have 4 more to replace them with so no worries! These are an excellent value and quality.

Sc8uu 34.35+/-0.15 by 30.13+/-0.5 by 21.44+/-0.2mm. Treaded on the flat side only M4 w/ 6mm deep, other side not treaded and is a smooth bore 3.28mm wide. Bearings have 4 rows of balls, and although I have not been able to test them yet, they do look good, ATM. These look like good manufacturing, and are exactly what I order. UPDATED: I was able to test them and they work great, great tolerances. Thanks, ZT Automations I will buy from you again.
