Query: Quality is subpar

My first, original, OEM pad, lasted for years until the hook and loops started to wear down - so off to Amazon to get the first replacement that fits my Ryobi - this one fit my model because I checked, unlike many of the above bad reviews. HOWEVER, I got about 24 uses out of this before the middle, rubber, plastic piece started shredding. Super pissed because this makes no sense how that would happen - 3/4" pieces started falling off while I was sanding - like either the adhesive or the blend of plastic had failed. Annoying as I should npt have seen this for a few years, if at all. I had to finish a job with the old OEM piece (no idea why I saved it) - As no one else is reporting this, I have to think this is a bad batch, or a bad vendor, but annoying nonetheless to have to order now a 3rd one...
