I have a Cyma CM028-S (AK47-S), internals jammed or broke or something. The external bits were great; nice fake wood, lots of metal just like the tm, powerful too (by poor mans chrono it would punch through both sides of a can, which was 350 fps or something). Then suddenly the gun just doesn't work, so I think it's the battery and order a new one. Gun still doesn't work, I open it up and find out that everything is working except the gearbox. But for the 2-3 months that I had it...it was awesome.
Getting it fixed now by JohnnyDo. Not sure what I'll do with it after that though...
