Query: Nice Looking, Low Quality

They look cool and are a fun design. However, the bonding on the back of one of them came off without much stress being put on it rendering it useless Even for $30, they seem like low quality. The site lists only a 90-day warranty against defects. If you are looking for some cufflinks you can wear more than say 5-10 times, I would look elsewhere. I think I only got about 5 days use out of them. Even at $30, that's $6 for each wear.
