I can't get enough of this gun! It is small and relatively light so maneuverability isn't an issue. I personally haven't had any issues with feeding from the high-cap but I usually use the 1500 round drum mag which is totally worth it. Seriously, if you get this gun get the drum mag, you won't regret it. The only real complaint I have about it is the small battery compartment which is just enough room to shove the battery in. I also recommend an extra battery or two so you can be sure you won't run out. Time for some pros and cons.
Pros:
Light, but still has a good weight to it.
Killer trigger response.
Great rate of fire.
Accuracy is great even from a distance. You can hit a target from 150 feet no problem.
Burst Fire is awesome.
Loud.
Satisfying to shoot.
Drum Mag.
Sturdy.
Cons:
If you have long arms, even on the longest setting, it could feel small. I'm 5'3 and it feels just right.
Small battery compartment.
Loud.
Friends will probably want to steal it.
Overall, I would definitely recommend this gun. Fun to use and better quality at a cheaper price than most brands.
