Alright, so around 4 months ago I got a shengshou v3 at icubemart and for some reason it just sucks. This was the first 4x4 I have cubed with, and out of the box, it was decently fast and overall just okay. But after a while, it popped and I ended up taking the whole thing apart because I couldn't jam the little pieces that go around the core back into place. So eventually I did get it back together by loosening the tensions and once I was done, I tightened it some thinking that would prevent it from popping. After tightening, it was pretty slow and locky, and what do you know, it kept on popping every month or so (I didn't use it much anyway), but I was able to put it back together fairly quickly. Also the corner caps kept on popping off like every solve which was very annoying. A few days ago, the whole cube popped once again and I just gave up trying to fix it and left it in a jumble of pieces. So what my question is after all of this gibberish is, do I have a faulty cube, should I just deal with it, or should I get a new cube, and if so, what cube should I get?
