Precision PRO Maintenance Kit

I use this 4iiii Precision Pro on a Dura-Ace crank, which is a very high-end and expensive setup. The battery cover broke far too easily – the design is much too fragile for a product in this price range. This part should be reinforced or completely redesigned. While the cover is listed as a spare, it is sold out, which makes the situation even more frustrating.

Yeah, Huizing on the driver side is very weak. Once you have a little crack, it is almost impossible to repair it. I’m not sure what to do.

The part that is way to brittle is never ‘in store’ and there is no way to order it. Why would you not support the many users out there wanting to secure the device?

when changing the battery on the drive side the unit fell completely apart but i'm not the only one reading all the bad reviews on this side, really a shame that this is not correct handled properly :-(
