At $10 a pop, even if it lasted 1 or 2 trips, you could still buy a dozen for the price of a Boga Grip!
There's no comparing the quality, one's a Mercedes and one's a Cavalier, but if your just trying to get a occasional large or toothy critter under control, I think it will last quite awhile?
If I was fishing for Steelhead, especially in moving water then it wouldn't be a contest, I'd want the Mercedes ;) ;)
