Hi everyone,
I recently bought a Dayan Guhong V2, because of all the positive reviews.
Out of the box, I thought that the cube felt better than my ZhanChi - but it somehow felt a little 'cheaper'.
I usually average around 25 seconds, but after a few solves I realised that my average had increased by around 5 seconds. I tried tensioning the cube tight, loose and a few different ones in-between but I just couldn't find the right tension...
I then decided I would take the cube apart and fully lubricate every little part. I took the core apart, removing the screws/springs/washers and applied a little bit of lubricant to them all.
When putting the cube back together, I realised that one of the core pieces didn't look right (see below)
Surely a defect like this can't cause such major problems with the cube (lock-ups etc)? I've asked the seller for a refund/new cube, but the last thing they said was that the defect isn't that bad so they'll just give me $6 ($3 because they sent me a white cube when I ordered black, and another $3 because the core is defective - I'm so frustrated... a new one from the same site is around $15, and they sent me the wrong one in the first place!)
Anyway... I don't know if I should buy another cube, a new core, or stick with my ZhanChi...
Any help would be appreciated!
