We wanted to produce Gorilla Bow for under $100 but the quality was not there. We decided to make a very quality product with thick aluminum bar and die cast ends that will handle over 300 hundreds of pounds in tension. The bands are multi-layer for safety and longevity all having a 2 year warranty and 90 day money back guarantee. We looked at lower cost design but there is plenty of cheap products on the market. This really can give you dozens of exercises and last for decades. Try out the Gorilla Bow!
