Untill now no need to use it! So no user experience yet hopefully the moment of use will never come.
Difficult attaching to the life vest belts as they seem to be of a bigger measure than the clip can have. The solution was to clip it to the oral tube.

I bought two at a distance of 5 days one of the other. Great appliance. However, I was really disappointed that with regard to the first purchase the product was presented as a hot pepper with limited time offer for the price of Euro 299.00. Only three days later I bought the second place on offer at Euro 199.00. I believe this commercial approach is not entirely correct
