The first thing I noticed when I saw the box was "Full Metal Slide".
._." = My Face when I realized I'd been scammed.
I soon recovered from this initial disappointment. It's full scale and shoots hard. Very accurate. I looked inside and found one or two more metal parts inside. Yay. Everything else is plastic.
Detail was alright on the outside; is very real looking at a distance. Close up: Obvious molding lines, random holes, and other bad things. There is a working Slide Release, Safety, and a working hammer, but the slide lock and breech locks are fake. Oh well.
Grip felt great to hold. Nice texture.
BBs get caught between slide and magazine, causing minor misalignment. No biggie.
There MIGHT be a hop up. Sometimes shots go up, but other times it spins down.
Bottom line - It's not nearly what the description claims it to be, but I find it worth the $29. If you want fun, buy an AEG.
I do, however, expect it to last a while as it feels quite durable.
