Is anyone having problems with the pump action of the Clenil inhaler? I am now on my 3rd inhaler of Clenil and sometimes it pumps well but others it hardly pumps anything out at all. I am sure it isn't my technique because I have used inhalers for years and have never had a problem before. I have also been told several times that my technique is good. I have taken this one back to Boots but the pharmacist has noone else using it so doesn't know if this problem is unusual but he is getting on to the manufacturer about it.
