Dropped one of my better ones under pressure,to say it went pop was an understatement.
The rubbish Contico ones,have a habit of popping off the hose,and spraying solution everywhere,as the hoses go all limp,after a bit of use,keep cutting the ends off,so it's tight again,but it does not take long before they go soft again,can't get a jubilee clip round it either,due to the design.
