However it would be unfair to only blame Pearl for this. Most manufacturers have one or two rogue parts or finishes on their high end drums. Remo hardware was notorious for stripping threads, there were the Premier oval tom holder brackets which have nearly all cracked now and even Sonor had BD legs that start slipping after long term use on the Phonic/Lite/Signature series, the use of the little grub screws on the 2 legged DW hihat stands, the completely useless round single piccolo lugs that Tama used etc etc and there are many other examples.
I do think it is beholden on companies to at least own up to the problem though and try to offer some help though.
I view that as a failure to take responsibility for the situation. In turn, it's neglectful of loyal customers and akin to saying "yes, those lugs are duff, but feel free to spend the equivalent of your kit's current value on more Pearl products to fix it".
So, in summary, my issue is that (admittedly some years ago) many of us paid good money for a high end set of drums. We don't expect them to become worthless during our period of ownership due to a manufacturing defect; especially so when, in a lot of cases, they've been very well looked after.
