I went back to the Apple Store and tried 3 new wallets (two ink and one Umbar). They were all weak. One ink case was slightly stronger, but not strong enough for me to feel comfortable keeping it. I also tried a few display wallets (which did not contain cards), I noticed that ink was consistently weak. however, Umbar and green were moderately stronger. Unfortunately, I was unable to find a new wallet with equivalent magnet strength. My guess is there is a quality control issue, as some display wallets had suitable magnet strength. I however felt bad for the apple employee and did not want to continue with the hassle of exchanging, opening, and then discarding new wallets. in the end, I decided to return them all. I’ll consider a third party case or wait to see if apple makes any improvements.Did this fix it for you?
