Phill it might just have been me.
"didn't get on with it" - this was the first time I had used it and I found it just a little less simple than the Halcyon one. The Frog one need me to either push the inflator against my teeth and blow or pull back on the collor - yes I know not very complicated but the Halcyon one was just blow.
Gareth kindly lent me his Halcyon one for the weekend and I am glad he did, it was just one less thing to worry about.
I'll probably keep the one I have labelled as a redundant spare but will buy the Halcyon's one for proper use.
It was probably me
I haven't heard anyone else say they don't like them.
