Nice little innovation. Expensive but worth it.
Serves the purpose, especially like it for deadlifts with short bands. There are also a bunch of other exercises that cannot be easily done with regular bands but Gorilla bow makes it possible like forearm curls, shoulder / chest press, bent over rows and squats.
It might look expensive but it's the innovation and flexibility that is worth paying for. The idea of stacking different brands and just using the ones you need for a particular exercise is brilliant. Saves a ton of time between sets. I usually have two 90lb bands and two regular ones ,.so I can easily do super sets.
