You responded in the most positive way when My USA product failed when using UK electric and were incredible in offering a free of charge replacement suitable for the UK. As a sleep apnea patient your product has cleared my nasal passages in the most efficient way and I have been very fortunate in being able to dispense with a steroid spray which was recommended by The Royal Nose, Throat and Ear Hospital in Kings Cross - London. As a result of using your product I shall suggest to the Hospital they recommend to their patients NOT using a steroid spray which has unleasant side effects and use your SinuPulse machine instead.
