I'm not sure if this has been posted before, and this is my my first post so tell me if I'm doing anything wrong.
I got the Qiyi Thunderclap before many reviews came out, and at the time it felt perfect, being about a 45 second solver. Then the factory lube dried out, and it's now quite slow.
I've tried wiping it with paper towels and washing it in warm soapy water to clean the lube off and see if it would speed up, which didn't work, and lubing it with weight 1 and weight 4.
I've also played with the tensions a lot. Nothing helped. The lube made the turning smoother, but it looks to me like there's simply too many contact points in the mechanism for it to be fast. But everybody on YouTube seems to have a fast one, so I was wondering what I could do to make it faster.
Thanks!
