Review about Fostair

Fostair works well when it works BUT the counter is useless! my current one has just run out with thee counter still reading 64 doses left. This happens with about half of the inhalers I use, It's easy to prove, when you inhale and are still struggling for breath open a new one and see the difference, instant relief, I believe this is either a design problem or a storage problem. Fostair is supposed to be refidgerator stored prior to use., WHY and I have bben given one from a shelf at the back of the pharmacy. I store mine in a fridge all the time as I can't find any info on how they should be stored once in use. Allthings considered a good but flawed product. I have run out so many times when the counter still says over fifty doses left it's a wonder I'm still alive.
