It would figure that just after I spend over $100 on a Boga Grip that I would find the "Berkley Big Game Lip Grip" for $30. Looks like it could be a pretty good knock off. I don't think it has a scale.
Go to http://www.eangler.com and type "lip grip" into the search box.
If anyone has been wanting a Boga Grip but didn't want to spend the money you may want to look into this thing.
Does anyone have one? Can you give us a product review?
