Bought this because it said Professional Formula and Wynns is a well known brand. Have used one bottle and I believe it worked because cloudy liquid came out when it drained. Also heater started working again. Good value only because it was cheapest I could find. The product you get though is not in 2 cans as illustrated but comes it two plastic bottles like you see in Halfords.

Excellent results on first use. New radiator fitted and a further dose will be used to get rid of the residual detritis in the engine block. So much better than using acid with it's known effects on the aluminium parts of the system!

Appears to have done the job, or at least I hope so! Time will tell.
