Soooo I've waited and waited and nothing ?!?

Is this first response?

take another one.

Yeah @acentimole

This was the only one I got @themommaoffour

This is has happened to me before. Call first response and they'll send a coupon for a new one up like 23 dollars I think. So yeah. This happens often with this brand

get a cheap one. they work better and are just like the ones from the doctors office

take another one as it's invalid, cheaper ones are better than first response
