"  Had multiple shipping companies break the system that I purchased but the customer support was phenomenal at Altitudetech.  They promptly answered all my emails regarding my altitude tent, altitude training and how to use the system, I can't thank them enough.  

After 3 months of using the system, the benefits were really starting to show, I won a 20m TT and I felt like I was flying.  In addition, I have been able to maintain my body weight of 150 without dieting and my fat percentage of 6%!  Thanks for a great product and customer support !  "
