I'm having an issue with my GAN 356 X Stickerless with Numerical IPG. I received it May 8 or 9, but I'd have to check to see which one. Anyway, ootb I did not have any issues, except for what you'd expect for an ootb cube. I broke it in over the next few days, and was actually doing extremely well. My previous best single and avg were 18.15 and 23.67 respectively on a(n) (overlubed) Valk 3 Power M, but on the fifth solve on the GAN, I got a personal best of 16.55! The next day, I got 16.40, and then on day 3, I finally got my first ever sub-15 solve (14.18) and a really "good" (see thread "How good is "good"? for quote) average of 5, at 20.93 seconds! My times improved substantially, but after 1-2 weeks, they returned to (slightly better than) normal, and on June 1st, I had my first significant problem on the GAN X. The Green-White-Red corner popped, but not in the usual fashion. The cube was tensioned tightly enough that I wouldn't have any "normal" pops, but the corner stuck out from the stem, and fell on the ground. After examining it carefully, I found that It had done a very clean break from the stem. The only way this could have happened, to my knowledge, was if the parts used to make the piece had separated somehow. I was able to pop it back in, but I kept experiencing problems with it throughout the day. However, since it dropped while I was solving it, and since I was outdoors most of the day it fell on the concrete, that could have been a factor. I also did an unusually high number of solves for me (140+) that day, so that may have been the problem. I was also experiencing minor problems with the Green-Yellow-Red piece, but it only stuck out a little bit.
As time went on, the problem didn't progress all that much, but it did stay as it was.
However, about 1-2 weeks ago (in late July or early August) it started happening with another corner (the Green-White-Orange one) one.
One thing that I've noticed so far is that all the problem corners are on the green side, but it might just be a coincidence.
If any of you have ever had a problem like this, or know how I can fix the problem without buying replacement corners, please let me know.
In (not exactly) dire need of assistance,
