Rated 5 out of 5 by from Does what it says Very simple to use and can be applied directly to the radiator, all the headers are included with the product. If applying to a new unfilled radiator, what I did was removed the bleed cap and the blanking plate, screwed the supplied adapter in one end, inverted the can and pulled the trigger. Refitted the bleed cap and blanking plate and then opened the valves. Turned on the heating and bled the radiator- all in all around 10 minutes from start to finish.

Rated 5 out of 5 by from Really quick and easy Really easy to use with a TP1 mag filter. Literally takes 10 seconds and is so much easier than adding fluid via a radiator. Seems expensive but worth it for convenience in my opinion

Rated 5 out of 5 by from Just the job! Comes with all the necessary adapters. Topped up a pressurised system in no time. Dead easy.
