Easy to use, great product
I was losing coolant from my Corsa and was sure it was the start of a head gasket issue. I read the reviews and used K-seal and after nearly 2 weeks I'm no longer losing coolant. Easy to use, simple instructions. Definitely has worked for me.

K-seal
Had done a 'sniff test' on the wifes focus and it showed a very slight exhaust gas leak into the coolant system which would explain the loss of power and overheating due to coolant loss. Purchased a bottle of K-seal and followed the instructions on the bottle, have done a subsequent sniff test and it is showing that at the moment there is no exhaust gas in the coolant, will update review after a few weeks but its is looking promising at the moment.

Reliable seller
Somehow the bottle looks bigger in the picture than the one that arrived - but if you read the label properly you will see it is a small bottle and in reality one doesn't need a large bottle to get the effect they want. It arrived either 2 oer 3 days after I ordered it - exactly when expected according to the ordering - however my car decided to die later the same day so I never got to try it out. Apparently according to everyone I have spoken to this is a good product. I will keep it now for just in case and being such a small bottle makes it nice and easy to store which is a bonus :)

Does what it says
Have bought and used this product before. Works for minor leaks; not if you overcook you engine and warp the head!!!!Now have one in the garage as a emergency reserve. Good product that doesn't seem to clog up the cooling system after use.
