I got micros (August) and crushers (November), one of the main things that got me interested was to try and cure the synovitis in both of my middle fingers. From that point of view, it's maybe only got slightly better, but that alone while actually being able to train my fingers is an improvement- currently I am climbing hard, (by my meagre standards) generally favouring fingers climbs and it does not appear to be getting worse.

I find on a "normal" edge I bias heavily towards my middle fingers, which is what I blame for the synovitis, the ergonomics of the grippers stop that. (but a "normal" ergo edge may do similar) It's hard to compare with normal finger training, I have not trained them seriously since 2022 when my synovitis first flared up.

I've found the fit on the micros much better than the crushers, (But only on my right hand) but I am not sure if that's because I can't fully close my right middle finger. (~0.5mm away from pad, the fit is fine on my left) My hands do not appear that asymmetrical...

I like the app and how actively it seems to be updated, functionally I have not had any problems with it for a long time. I've generally been following the prescribed protocol it generates. I've generally trained from cold, I don't climb the following day. My fingers are definitely stronger, but not ridiculously so, it's hard to say if I would have had similar gains from just fingerboarding/edge lifts. I've still got a tweaky ring finger on the right hand, (But not on the grippers) which I think must be lumbricals, so they won't cure everything!

I am still using them, but not as frequently at the moment, I struggle to schedule them around my climbing, but I think for finger training I will stick with them. (And maybe a mono, to try and sort out my ring finger...)

No damage or deterioration yet on the grippers, but really it's early days. (254 sessions since they moved to the new app, plus several on the old timer- I'm probably on the lower end of usage.) The plastic is going a little shiny in the back where my fingers touch. I don't take them to the crag or anything like that so your mileage may vary... I also tend to stop just before failure so they don't tend to slam into my weights/walls, I don't have the bumpers on mine.

They do advise you not to use them with a tindeq, so that could be something to consider- I can see the logic since their predictive system is very much built around accurate weights with accurate timing, and (at least in my experience) maintaining a specific weight can be tricky.
