I've had one for awhile now and just needed to change the battery. The tiny screws and special screwdriver are definitely challenging, but other than that it's been great.I got the ridge wallet with the AirTag case for Christmas. Unfortunately, the screwdriver came defective so I haven't been able to attach it yet (or replace the cash strap with the money clip I also got). I'm trying to get a replacement screwdriver. I like the Ridge wallet though.
