Legit Product
All anyone needs to know is IT WORKS. As long as the leak isn't a gaping hole. And it did not clog my heater core.

Actually works
I was very skeptical trying this First I’ve seen so many horror stories of using the liquid stop leak and it plugging things up and over heating and I saw this and it had good reviews and I didn’t think it would do anything I have a 08 tundra and I thought the lower radiator hose was leaking so I changed it out but still had a small leak in the same area Well I realized the radiator itself is leaking and looking a little rough So I decided I’d try this since I’m working 7 days a week currently to get me by I followed the instructions exactly and it’s been a week now and it actually works I have no issues with overheating nothing is gumming up I’ve checked the fluid several times and all I did was turn a gold color Still running the same temp I’m impressed Time will tell how long it will actually last but I might get lucky and it fixed my issue

worked for the camaro
Bought this as an alternative to the gm brand additive that is in the camaro. Seems to be the same thing. Works

Works great. I use it in all my vintage vehicles
I have 4 Flathead powered vehicles with old radiators. I use this in all of them just to help with little pin hole leaks. This stuff works quickly and is good to have around if you have an old car or truck

Use the liquid form.
Bought this to seal a pin size hole. I went to use it stated to insert into the filler per the directions. The pellets are very large and just fit in the filler opening. I only got 5 in. Ran for 10/15 minuets. Well the wife went to work the next day and on her way home the upper hose blew off. After I got there and started looking at it I found the pellets had just stayed in the filler neck. I needed to use a screwdriver to open a hole so I could fill it up. I guess if I had to do it again I would use a liquid.

directions are bad
I have 2 problems with this product:#1 the directions say put one tablet in per gallon, which is WAY too much because it produces copious amounts of sediment in the system. Just 1 is sufficient.#2 Bars has umpteen products on the market in many forms for the every same same issue, which hardly engenders confidence in any of the products because common sense tells me that if any of them work at all, there is one form that works the best, which is obfuscated by the claims of each product.To sum up, I personally do not appreciate nor trust the obfuscative marketing strategy of this company regarding it's radiator leak stopping products.
