I have one. Mine is about 3 years old. I have over 1000 rounds through it with no problems except the safety. That's a must to get fixed. Since it's a DA only, the safety is redundant and not necessary, in my opinion. Older models had some problems with cracked frames. Mine is a newer version (can't remember the first two digits of serial number, and it's too dang cold to go out to the truck and look). I've been using it as a back up, and it pretty much stays locked in the truck.
You'll hear a lot of good and bad. Asking open questions on a forum like this will get you many varied answers. Those who have experienced no problems will tell you it's the best thing since sliced bread. Those who have problems will tell you it's a piece of junk, and about anything in between.
I can only speak from my experience. I've fed it a mixture of ammo from Wolf to Blazer to Federal Hydra Shok. I've not had a failure yet. Right now, I'm feeding it reloads for range rounds. No problems. I shoot it at lease once a month - 50 or so rounds. 50 is about all I can handle before my hand feels like it was slammed with a hammer. It's a light gun, and not meant for extended shooting. Would I bet my life on it? Yeah, considering I've had no problems to date.
I cannot speak to customer service since I've never had to use it.
Would I buy another one? Probably. As someone else stated, there are a lot of guns out there under $300 - $350 that have a better reputation (and a few that have a worse reputation), but all-in-all, I'm pretty satisfied with it.
I would not consider it particularly "pretty" and the finish could be a little smoother - more rounded corners etc. It's very concealable, and comfortable to carry - depending upon the weather and my clothing, I sometimes carry it instead of my 1911.
Hope that helps a little, and is a better response than "it's great" or "it's a piece of crap."
