I have one. It is a $30 knife, definately not a Micro=tech or a Benchmade... But then again it is a decent $30 knife. The ergos are good, it was sharp out of the box (I steeled and stropped in on cardboard and it is now shaving sharp) there is no wobble, and as far as the lock goes..."every gun is loaded & every folding blade is a slip joint" No I haven't asked for trouble and beat it on a table. This has been my everyday beater for a year. If I loose, break or dump it I won't be heartbroken.
The whole idea is to get the best value for the amount of money you can spend.
If you just can't wait (& save) to get something better, you could do worse.
