Sentinel Rapid Dose X100 Inhibitor 400ml
Having read other reviews I had high hopes for this product but it didn't live up to expectation. Neither of the two adapters properly fit my brand new radiator. First I tried the narrow one in the bleed valve but no seal could be made. As soon as the taps were turned back on water poured out around the adaptor. I then tried removing the nut to use the other adaptor. Even though it was tightly screwed in once again when the water was turned back on water poured out around the adaptor. I tried using the can anyway but I am not at all confident any of it has stayed in the system. Feel this was a waste of Â£19 as I am going to have to buy more to do it the old fashioned way.

Very impressed with this. Very clear instructions and surprised by the little rubber bean in the small folded up paper which is designed to acts as a one-way valve in the fill tube. Just put it in via the circuit fill valve. Simple and easy.

Expensive alternative for seal
Good for sealed systems with no alternative access point. Free dosing tool a bit naff. I have a kit and always use it in preferance.
Use it manly as a get me over when no way to get chemicals into a heating system.
Very expensive for what it is so prefer to use a towel rail or peace of pipe and 3/4 treaded elbow in vent plug of a radiator.
