After reading too many reviews on this gun AND being more expensive. I figured it would be ok for the limited use I carry out. So far it has worked flawlessly for me. With the right pressure, it sinks easily. My only complaint is that since this gun doesn't have a scratch-resistant tip, you have to be very careful with softwood. Once you get used to the slight pressure, you're safe. And based on what others have said BE CAREFUL WITH THIS GUN. Security can hardly be called security. It's very easy to shoot a pin in the air when grabbing a gun.
