I've actually owned one, and this is my experience alone.
The 9mm is an absolute jam-o-matic. I don't expect miracles from a $170 gun, but I've had more reliable ones that cost less.
If you're looking at it as a home defense piece, you'd better buy extra magazines and practice clearing it.
As was mentioned, cleaning requires a hammer.
I wanted to like this gun, and ended up taking a beating at a pawn shop, because I dislike paperweights laying about.
