I use the PS 20th anniversary DS4 right now and I've been using it for awhile now.
#INPUTMAPPER DS4 TRIGGERS NOT WORKING PS4#
but since the PS4 came out I've broken at least 4-5 DS4 because the R2 and/or L2 trigger buttons snap to the point where they are no longer functional. I haven't broken a DS4 in quite some time. These things work like a charm and i've used the same 2 sets with every controller I've had. I bought these after my very first DS4 started to lose the rubber coating on the analog sticks. I just settled for some analog nubs, which I've actually come to like more than the supplied grips.
The ones where it happens outside of warranty, like it did for myself on two controllers, happened after the first year, and Sony wouldn't replace them. While the issue should have not happened on the scale it did, the first one I mean, Sony did offer replacements which you could actually get through GameStop, and most people I've seen complain about it seem to not have taken advantage of that when asked. The second usually shows up soon after purchase, and is covered under warranty. The original problem was covered under and extended warranty by Sony, from 90 days to one year.
The cracking is a similar issue, which can lead to it tearing, however it comes more from environmental flaws introduced through normal wear, and I'm not exactly sure why it would be an issue. however, the actual problem with the tearing has been remedied.outside of if they have a batch with poor quality control again, which I imagine is feasible. I'd imagine some of those are still out in the wild for sale as well. The tearing was poor quality control on the initial batches of DS4's, some included with systems, some sold seperately. One where it dries out and cracks.which I assume is the problem The infected had. One where the rubber tears, and basically comes off.
