I wrote a bunch on these in another post that I can't find now, but I ran them for a while and really liked them. I have ulnar nerve damage in my left hand and they helped better than anything else I have tried, although significant changes in diet and exercise habits off the bike have reduced it dramatically since. The surprise for me was how they helped with control of the bike, it feels kindof like adding CushCore or more suspension, it gives the bike a bit of stability it feels esp. on chunky stuff. There are a lot of benefits for people that don't have issues like me, but they definitely helped me with my hand pain.
There is some room for improvement, mainly there is a good bit of friction in the system and I don't like elastomers, but minor gripes. The only major complaint I had is that I felt the softer two elastomers were kindof useless, I'd rather see more granularity in options around the middle firmness setting, but the two elastomers in the middle (yellow and red) were the ones I found the most useful.
If you have hand/arm/shoulder issues, they will probably help. They also have a 30 day return policy ([https://fasstmtb.com/pages/3](https://fasstmtb.com/pages/3)), you can try them and return them if you don't like them or they don't help. Their support is great, as well, I spent well over an hour on the phone with one of the owners discussing their bars and our hand issues.
Not to steal Andrew's thunder, but those are my impressions. I'm anxious to hear his thoughts, also.
