Think it works well. Can't hurt if your coolant is ancient.
I didn't have any real blockages but used some of this in a 20-year-old car before I changed the radiator.Lots of crusty bits came out with the coolant - but I had to change it again as another job meant draining coolant (and reusing is just jank!) and more definitely came out again. As it happens, the NEXT time I did this it was basically clean; so I wouldn't worry - maybe do a second flush with only coolant/de-ionised water if you are using this.I can't say for certain but the same car has had heating issues since - only half the vents will blow heat. Probably unrelated as I did flush the heater matrix and nothing came out.

Might need more time and temperature?
Had mayo in my coolant due to head gasket failure. I followed the instructions and it definitely shifted more muck than a water flush alone, but I think it would be better if run in the engine for longer and at higher temperature to shift any oil stuck. But cheap price so I'll probably buy more and give it another flush when I do the oil next.
