I have been purchasing my inhalers and antibiotics here for several years now, never any problems.
My MD looked at the inhaler and said its fine, he actually took the website info to give to his patients to order their inhalers.
He is a pulmonologist and said there is little difference in the meds.
I was concerned using my credit card for a foreign transaction, no problem at all.
I have a cousin who orders here as well, she told me about it, I say together we have been ordering for about 5 years with no problems.
I did loose one shipment, they refunded my money immediately and helped me get another shipment.
The only downside is the time it takes to get here, usually 2 to 3 weeks, so I order extra!
My inhaler here is about $4, in the states WITH insurance, its $50 per inhaler.
I highly recommend ADC to anyone!
