I've been using ESI grips for several years on my older bikes, bought these to replace the Ergon grips that came on the Canyon Roadlite I got last year.
The Ergons tended to lock my hands in one position and put pressure in all the wrong places. The ESI grips are a vast improvement. I can ride 40 miles easy, no numbness.
I've been looking for a larger grip to fit my big hands. These are the best fit so far and seem to be very comfortable. I've only ridden them a handful of times, pun intended, so I can't comment on longevity.
These are good grips for somebody who wants a girthier grasp. They're firmer than I thought - not to be confused with those foamy grips like Ring Ding cake. These feel great and seem indestructible. Colors are a plus.
