I have one myself and i really do not like it at all. You cannot feel the pins at all in the locks. The handle is so heavy you never really get the feel of the pins. If you are just getting into lock picking i would highly recommend getting individual picks so you can lean the feel of the pins and tension inside the lock. I got one of these a long time ago before i had individual picks and man i had a really hard time leaning with it. now i can pick better with the individual picks maybe because i had to lean with that heavy thing but i dunno. Maybe in the long run it is good but really i would stay away from it until you are good at picking and you can have one of those laying around just In case you lock your self out or someone you know does. that way you do not have to go all the way back home to pick up your normal picks. But be careful because in some areas picks are illegal to carry and i know if you have on of those it is just so easy and convenient to keep in your pocket or on your key ring.
If you do end up getting individual picks try Digital Blue's guide on lock picking it is really good and great for anyone that wants to lean how to pick.
