I ran my CM 020 mechbox (the one that comes with the CYMA AK47) for 3 games hard so thats around 10000 rounds or so with a lot of dry firing. I took the bastard apart I noticed minimal wear on all the parts except the spring guide was cracking...but a cracking spring guide was bound to happen.
Pros:
Upgraded already
High ROF
Cheap starter gun
Mechbox grease tastes delicious
Cons:
Plastic bushings
Cheap cylinder head, air nozzle, and spring guide
Poor air seal on lemon guns
Non TM compatiable Hop up
Mechbox grease is addictive
