I had been interested in these for quite a while, but my interest piqued when I saw an athlete at the gym who I admire using them. I had seen the two and three finger versions, but she was using the four fingered "glove" version. For myself and kipping, my ring finger and pinky finger take the most abuse.
Anyway that arrived as quickly as expected without much packaging fanfare. The finger holes were cut really small and I realized after that this is intentional so that I could expand them for a customized fit. So I got out a small pair of scissors and expended them until they felt right and then cleaned up the finger holes with a lighter.
I was a little concerned about the size and maybe should have gone with a large, but I think they will break in well. The website does mention to cheat down as they will stretch.
So far so good. I felt like I had a good grip on the bar when kipping and barbell movements. They seem to hold chalk well and look good too. How durable they are is to be determined.
