Just got diagnosed with sleep apnea went to Cpap Store USA in Las Vegas and these guys took great care of me. They staff is super knowledgeable and they took the time to explain every question that I had. Im so excited can't wait to have a good night sleep. I checked a few places in vegas and on line but nobody answered my questions and a lot of time even didn't return a phone call. The main reason I purchased there is the no pressure environment and I got all the answers and price I was comfortable with and was out of the fast. Thanks you guys you are awesome!!!!!
