Should I get the G&G GR15 Raider Carbine Electric Blow Back Airsoft Gun (Black)?

I've been getting into airsoft more and more. I've been playing for about three to four months. I've been using my friend's old M16. It is unreliable because of the age and the use of the gun so I've been looking into buying my own. I'm a little wary of the gun I should I get in fear it may be unreliable and break down easily wasting the money I've spent on it. Many of my friends say G&G is top quality. So I'm considering on buying this gun G&G GR15 Raider Carbine Electric Blow Back Airsoft Gun (Black). I've looked for reviews, all positive, but I'm curious as to what others have to say. What are the pros and cons?
