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 had to exchange my wallet because they asked me to provide pictures of the wallet and they said it appears I have stripped screws. Which is odd because it's brand new. But whatever. I'm definitely going to order extra screws just in case.
I got my replacement today and I was a little annoyed because the front carbon fiber plate had a long scratch on it. But I really don't feel like sending it back, and it's going to get scratched up anyway. Maybe I'll send them an email and they can give me a discount or something, hopefully.
Anyway, I installed the money clip and the AirTag carbon case. It was intimidating, but mission accomplished. It isn't as bulky as I thought it would be. I like the fact that AirTag case is screwed on. I had a cheap AirTag wallet with a slot that just snaps in, and one of my worries is that someone will just steal the wallet and take the AirTag out. But if someone steals the Ridge, they'd have to find the special screwdriver needed to take it out, and they're not that easy to find.
