Partially good
i ordered the product first time it was delivered, and it was great. but when i place an order for second time i didn't receive it, but thanks to the Amazon customer care that step into the issue and the seller refunded me back my money, despite all that i recommend the seller and the product and hopefully i will reorder the product again if need be

Incredible stuff!!!
Purchased this in desperation as my motorbike had lost compression in one of its cylinders so it was this stuff or bike sold as spares and repairs . Used 3/4 of the bottle and the bike is running like new..... can't fault it!!!!
