I have found tons of uses for this product and thus only need two hands to work on guns. Did not realize it at first, but the barrel can be pointed either way. I use the unit backwards for laser bore sighting for instance.
Pros: Easy to setup and use. Very utilitarian. Can point most gun s either way depending on position needed.
Cons: Could have height adjustments built in to nonclamping end and middle hump. Middle hump should also be removable and/or front/back adjustable..
