Works great but needed to be modified
I was able to get this to work with my V groove 20mm extrusions, but I had to modify the roller body a bit.I could not get the two adjustable rollers close enough.There was just not enough adjustment range. I took a 1/4 inch rat tail file and elongated the two holes just enough so that I could get the proper adjustment. It was easy since the body is aluminum.The rollers roll really smooth on my V groove extrusions.I am using this on a DIY 3D printer with a MK8 extruder

Can't be tightened enough to fit Openbuilds linear rail
Tested on 2020 V-slot of an Ender-3 printer, and it seemed to fit well, but official Openbuilds V-slot has a slightly deeper slot, and it was not able to be tightened enough.After filing out the holes on the fixed side and shimming the screws closer to the middle by 0.5mm, then it fit both the generic and Openbuilds V-slot.

Sloppy fitment.
After adjusting the wheels as close to the v track as allowed it was still lose. Maybe the mfg should update there q.c. program. Not useable without some tooling.

Tolerances are bad
Well made, good design, tolerances were wrong to grip the vslot extrusion I had. For the price I don't mind.

No eccentric spacers
It don’t even has the eccentric spacers.

Total crap.
I work with v slot and open builds on a regular basis parts on the regular in my prototyping shop. This product will not tighten on Open Builds v slot. I have completely tore apart and reassembled this item and cannot get it to fit the rail snung. It’s worthless.

the bearings grate and can't be used
I ordered 4 of these, and 10 of the 16 bearings were grating. I've returned them. At £15 per unit I hoped the quality would be higher. Avoid these.
