Reviews
Cal-Shot Total System Protection 300ml is rated 3.7 out of 5 by 6.
Rated 1 out of 5 by from Useless product This product is about as useful as a chocolate teapot, in-fact at least a chocolate teapot would taste nice! used provided attachment to attach to the radiator and like other reviews stated the inhibitor just leaked out onto the floor! Would have taken this back but the liquid all spilled out on my floor!

Rated 3 out of 5 by from Not that great using filling loop. I bought this last week and it leaked when trying to introduce it through the Filling Loop. I drained and flushed the system first and then followed the instructions carefully. It leaked when squeezing the bottle gently. I checked that everything was tightened and started to squeeze the bottle again but still it leaked. I must have lost half a bottle of the stuff on the floor. I ended up adding it through one of my radiators using a funnel.
