I've already got a small pocket-sized Collins Crossword Dictionary that's superb but limited in categories so went for this as a fuller reference book of lists. Its certainly got more lists but never seems to have the ones that I need and is much more difficult to find the list to look through. I've gone back to using the Collins pocket-sized. Disappointing.
Worked perfectly to enable a leaky radiator to be changed without having to bleed the system. Make sure you've got everything ready to go though because it only lasts about 30 mins max. and only enough in the can for one freeze!
