Seemed to work
Cleared a load of gunk out after use. Unsure of how effective it was, but for the price it’s worth using it every time you flush the coolant

Worth the Money
Whether it's snake oil or not, I don't know, but no harm in using these things every now and again just in case.

Decent radiator flush
Bought this one as its a well known brand and for use in my 1968 classic., so didnt want an unknown cheaper product in the car. Enough for 12 litres capacity so have some left for another time. Seems to have cleared a lot of brownness in the radiator

Does what it says
Seems decent enough. Put the whole lot into a 4.9l capacity Corsa and ran for 30mins with the heaters on full blast three times to ensure a deep and thorough clean. Ran 16litres of water through the rad after and then three more ten minute sessions to rinse through the block. Still slightly soapy and I'll give it one more "hot" rinse before refilling the rad with a little over 2l concentrated antifreeze. Hope I'm doing this right as never done before!

It didn't make any difference It just foamed up I left it for two days with no result And when cleaning the water cooling system I had to brush it twice for the foam to go away
