"I was happy with this gun, I think it's worth the price but it had some flaws.
It's simi auto stopped working one day randomly and I've tried to open it up and take a look inside but this was neerely impossible to do so without braking something. Also when firing full auto it tends to spit BBs, 2-3 at a time. Apart from those flaws it's a solid gun as long as you don't require simi you should be good, it's rate of fire was nice, it's pretty a sturdy gun and fps was exilant.
I feel like with enough research you could do better however this gun was worth it for me.

"put about just over a thousand rounds through then the gears were not meeting up and the motor would just spin freely. tried opening up which i found to be impossible. when putting the front pin back in the whole was not drilled straight and when pushing the pin through the metal broke off. terrible disassemble and terrible machining job.

-super high ROF
-overall great shooter.

-terrible build quality
-semi-auto fire would fail at times and i would use full auto instead.
