    Very positive experience with this seller. There were carrier-related problems with the delivery (not their fault at all), but they still worked quickly to address the problem. When it arrived, the item was well-packaged, and the seller communicated appropriately to make sure everything worked out. Hope to do business with them again.

    Good seller, my ordered was as advertised, except for it came in 2 packages 2 different days. This certainly could have been shipped together, as the box was big enough for about 8 or 10 of the extract bottles. Again, great seller, will do business again.

    Great bottle of hand wash. Seller is top notch in honesty, packaging and speed of delivery. I ordered two . Seller made mistake and only sent one ( hey stuff happens you know!) But promptly responding with apology and made up new package with second bottle and I just received it . All is well thank you for having the integrity to deal with this issue professionally. I will save you as a seller for sure!

    This product works and does not take much time to stop engine coolant leaks.

    Product Works!

    I was as skeptical just from the looking of these tablets. The car is a 96 Buick Skylark, transverse engine, with the leak coming out just below the crankshaft pully. This leak was dripping at a rate that would drain a gallon in approx. 30 minutes. We put two tablets in, drove 20 miles, let is sit for 1 1/2 hours. Started up the car and the leak was gone. 3 weeks later and still no problems.

    Great Product!!

    Got the GM sealant tablets. Read all directions. My vehicle does not have a radiator cap. Crushed tablets, dissolved them in warm water and poured in coolant overflow tank. Drove around for forty minutes. LEAK GONE. Great product!!

    No Coolent Leaks

    Restored 1987 Buick Grand National not leaking Coolent. I put the tabs in a shop rag and gave them a couple of whacks with a dead blow hammer and installed the results in my lower radiator hose; the concept came from the Buick Grand National forum with the idea being that the tabs would go through the engine block before they went through the radiator - no leaks.
