This thing is certainly not going to stop a dedicated thief but for $37 it's a nice little locked container that you can throw in the car and comes with a cable to attach to the seat frame. Probably not that hard to break into but better than nothing. Would be nice if it were CA DoJ approved so it could serve double duty for home storage, but for that you need to go the next model up to the microvault which is substantially heavier and costlier.
Pros: Compact, relatively lightweight, inexpensive
Cons: Not a CA DOJ approved locking device, not particularly secure
