It worked for awhile and I purchased many shows and movies from them. Then one day it started not working by constantly buffering and asking me to switch to SD or HD (even though I paid full price for HDX). I contacted customer service through e-mail multiple times. They asked me to reset my router and do numerous other things. None worked. My internet is speed is steady and fine when I do speed tests and way beyond what is supposedly a "minimum requirement" for running HDX. I asked if I could get refunded for my purchases so that I could discontinue my account with them and they said that they will not refund anything. Terrible business and terrible ethics to charge people for a service that they can't use because of problems on the business's end. Will never buy from them again.
