"Am writing this to tell people not to bother with floplast stop ends. Have used floplast 22 and 15mm stops on 6 occasions and jg many other times. floplast stops tend to leak when reusing and can be very hard to get off. This has happened several times but has never happened with the JG. They may be a bit more expensive but I would not touch the floplast with a barge-pole now."
"Only bought these as the Speedfit end-stop I had been using as a temporary stop on and off since 2002 got trodden on... Great for temp stops as they come off easy, wouldn't trust them long term personally."
