I use 99s at the park and using the 93’s when I’m skating most other things- these are like 3 sessions in and looks like a piece peeled out
This will happen to any brand wheel and almost any duro as well - seen a lot, especially where some sharp edges on things take chunks out of wheels, or even just power slides on sharper edge road surface.
As much as some brands will replace wheels for people (more out of goodwill than anything else), it is down to the user and how as well as where they skate, more than anything to do with the manufacturing or production of the wheel itself.
One guy I know who constantly complained about his wheels of a certain brand went through maybe four or five other brands just because he said this brand was total shit or something like it - then had similar issues with all the other brands as well over a couple of years. Turned out it was mostly due to screw edges that were sitting out a bit on his home made ledge box, but it wasn't until others skated the ledge box and had similar things happen.
The whole time he was blaming the wheels, for which I did call him out on it and then just ignored him. Some people just can't be helped, but any which way, it is more just an unfortunate situation of the environment. On road surfaces I can't even feel chunks out or flatspots on some wheels, but I can absolutely feel every little issue on smooth parks or my ramp.
