I went for this rim because I wanted smaller diameter than stock Fanatec 32cm on Porsche 911 GT3 R.
After first sessions I am impressed. No, that is not proper. I am in love. The rim has incredibly great ergonomics: recesses and bumps exactly where they have meaning. You just put your hands on it and it becomes the part of your body: not fighting with deathgrip, not trying to find position for your thumbs. Absolutely great stuff, worth every single penny.
I was afraid of the plastic grip because I have always been a gloves dude, but worries are gone. It feels great, the plastic is exactly right mixture of softness, grip and firmness.
I have bigger hands, went for 2cm spacer for Fanatec BME. At first sight it looked too tight, but it does feel pretty OK when riding. I sometimes touch these corners next to 2nd row of buttons, but no big disaster, it is just there.
Also massive kudos to Zach who predicted I wanted 45mm bolts, not 40mm I ordered because of miscalculation so he sent me an extrapack of these longer (I needed them, oh yes I did).
Love this wheel. I really do.
