I have one and love it, although I try forget how much it cost!
Although it’s about 10 months old, I’ve not ridden the bike with it on more than 3 times since so don’t have anything solid to report.
It does work really well though and I even picked the bike up by the saddle with it down the other day.
The post moved up about 2 inches and I wondered if it would then be all squishy.
It wasn’t and still works perfectly. The other normal reverb I have is squishy because of this, so points to the axs version. I believe newer normal ones might have addressed the issue though.
All in all it’s great if you can justify the cost.
I’m thinking of going to the axs shifting, so the opposite to you. Lol.
Like the feel of Shimano shifters though, so holding off for now.
