I began purchasing XL and protechtor cases in 2007. We have now travelled to Cuba and Hawaii with these cases, and they have held up better than any other product we have used. These cases are made for hard travel – busses, airports, etc. They are easy to load andthe straps work!We take our equipment out over 10 times a school year, and we have yet to replace anything due to damage.(cases or drums)I am now looking forward to purchasing more cases for our latin percussion now that you offer hard cases for congas! These cases are so good, my collegues now borrow them from me for their international trips! Keep up the great work!
