Aside from being the dodgiest named tool around, I bought one yesterday and - I guess - will return it tomorrow.
Was scepitcal - and even a little concerned but I had a good plan B and to be honest I just fancied trying it for a laugh as it looked fun.
Gave it a dry run on an off-cut of some l speedfit pipe and seemed pretty good. Looked compressed enough to stop flow (although I didn't blow down it.) On releasing it it barely left an impresson on pipe, a little mark but integrity looked good. But when I tried it on some live hep pipe it didn't work. Tightest I could do it by hand still didn't stop flow. Fairly new pipe, I'd say no more than 8 yrs old, only 15mm and it was tank fed so low pressure. It looked like it compressed it well but it didn't stop flow, not even enough to reduce to a dribble for making do and doing work anyway.
In the end I released it and did a live catch but bit baffled why it didn't work. Are these just rubbish? Any success stories?
