I read reviews before I bought mine, and IIRC, early failure was a common complaint about the DiamondClean. I was interested in it because of the charging glasses, but decided to get a model with standard chargers instead.

I’ve heard bad things about the DiamondClean. I got one of the cheaper models and haven’t had any issues.

I’ve accepted that I’m just along for the ride. No point in stressing out if I can’t do anything about it.

That explains a lot. The last package of Duracell batteries I bought all died before their expiration date. Store-brand is better than that.

Last time I had the pads on mine disintegrate, I found some replacements that were made of real leather. I haven’t had to replace them since. Some brands also make fabric pads; I’m sure they probably last longer than polyurethane, but I would expect them to wear out eventually.
