The big knob on my unit will often incorrectly register rotations. You spin it one way, but it registers a spin in the opposite direction. And it can sometimes take three or more spins before you get one that registers correctly. The big knob is also a lot looser. The two smaller ones are great. Solid and accurate. But the big one wobbles.
Use it for art and programming and I love it, feels solid and the knobs are well made.
I used VIA for setting up binds and macros and had no trouble with any of it, instantly recognized.
I didnt know how to use VIA up until recently. Sorta has just been a paperweight. However now that I have a greater grasp of VIA, I've been able to turn this thing into a workhorse for productivity and getting things done quicker. Especially with writing. Other than that, it's nice to fidget with.
Good buy.
