OK, here's a quick review from a low mileage tier:
1. I like the simple ergonomics of rotating a level straight head vise for 360* viewing & tying access.
2. The four corner plastic nubs on the base bottom keep it solid steady in place on table top.
3. Jaws work OK with #2 & smaller jig hook light heads, tho the lock down cam has a bit much play requiring perhaps extra jaw tightness.
4. The bad part: the slot grooves in the jaws for larger hooks are useless with Sickles - unable to securely hold a 3/8 oz. 1/0 heavy wire Sickle head in a horizontal shank position anywhere in the jaws. In addition to slipping, since larger hooks are partially in & out of the slots, saltwater hooks finish gets damaged. Positioning hooks outside the slots nearer the tip of the jaws there is not enuf bearing surface to grip larger hooks, even with enuf jaw pressure to deform the hooks.
I am somewhat able to hold the jig in place gripping the hook between fingers while wrapping, but its inconvenient having to hold material in place at the same time.
