Due to a weakened physical condition I do find this product to be very useful if not as compact as it's two smaller cousins but I knew that going in. The distance that it covers using only the device to do the work is more than equal to the next size down which has always been my mainstay. I do not see the product having anywhere near the life5span of the smaller units as there appears to already be a weak point developing in the upper middle section of the arm. Am used to playing tug of war with my woofs with these so perhaps I am being overly harsh.
