I have ordered from HME medical shop twice and I have to say they are very reliable I live in Caif. And ordered a conserver on Monday the 17 I received it Tuesday the 18 at no extra charge I actually ordered online and it was my mistake so I e-mailed and Michael Wise e-mailed me back this was on Friday the 15th so I called and spoke to Ann on Monday the 17th told her what happened and she made sure I got it right, I would highly recommend this Medical shop you can't beat the prices they are way lower than any competitor, I will definitely order again.
