Bests & Worsts Reviews from Amazon

I bought this back in June and I loved it, instantly became my favorite controller I ever bought. Great price, it feels almost as good as a standard Microsoft controller and I can no longer go without the paddles. Thumbsticks felt great, bumpers felt better than original, buttons were crisp and responsive. Build quality really feels superb. One weird thing to note is the USB port - there's a little notch put there presumably to prevent the port getting damaged from the cable wiggling around. The included cable fits well but makes it so most other cables won't fit. It wouldn't be too hard to remove that notch but it should've been opposite - put the notch on the included cable and a hole for it on the controller itself, so any cable could fit if need be. First thing I noticed - audio through this sounds like crap. I'm not an audiophile so the sound is OK to me, but there is a constant electrical buzzing that you can always hear. It's nice having the option there, but it's pretty bad. I haven't had any problems with the mic as far as I remember. Within a couple weeks of first using it, I start noticing the Xbox guide button was hit or miss. I would tap it, nothing would happen for a few seconds, then a screen would appear asking to shut down the Xbox (as if I held it for 3 seconds). That gradually got more and more noticeable with me hitting it 5 or 6 times with no response, holding it down fairly hard, then tapping again before it eventually activates. By the start of October, it works maybe 10% of the time if I'm being generous. Very frustrating if I'm trying to screenshot quickly or something. By 4ish weeks, the left trigger began randomly activating (so I'd repeatedly go from aiming a weapon and back to normal, several times per second). I'd have to mash the trigger to make it stop, but it would return within 10 minutes. Pretty common issue and ruins the game when it comes up. The worst part - which prompted me to write a whiny review - is the right thumbstick. The internal mechanism is absolute trash. I noticed slight drifting after 6-8 weeks, and it quickly worsened to the point that I can no longer use the controller. I opened the controller to inspect it, I can't physically see the problem but it's crazy loose and never re-centers. I tried blowing the gunk out of it, putting in rubbing alcohol to clean it, and shaver lube to see if something was stuck but no luck, it's still just as bad. The left thumbstick is great however, very tight and smooth to move. What sucks is that zero of my Xbox games have any form of deadzone adjustment, so the camera is constantly, constantly drifting up or to the right. I tried to get decent pictures of how bad it is - these are just from moving the controller back and forth, the thumbstick is just that loose. Update: looked closer and discovered the thumbstick sensor/mechanism is a different size from OEM, by a millimeter or so. Same pins and same shape, but just barely incompatible so I couldn't get a replacement to fit.
