Simple and easy Clear instructions and good fittings. Absolutely ideal as you need no tools to dose the heating system. 27 Jun 2015
Easy For A DIYer Just used this product. Very simple to use, instructions are clear, adaptor does what it is supposed to. Used on a new double rad and initially had a slight leak from the bleed valve, then cut the adaptor down by about 2mm and created a better seal. Voila no leak. Dosing takes 30 seconds and the whole process is done in under 10 minutes. Easy. 25 Feb 2015
Poor experience 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 £19 as I am going to have to buy more to do it the old fashioned way. 18 Nov 2014
Wow. Impressed 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. 2 Sep 2014
