It does what it says. We put it in a punctured tire, went to the first gas station at 9km and deflated/inflated the tire again as the instructions say. We returned from Corinth to Athens without any problem.

The vulcanizer couldn't find the hole because of the foam that went all over the inside, so every time we go for a tire change.

Unacceptable build quality, the part that screws into the valve is plastic and broke during screwing, without applying much force. Money wasted

Screwed easily, inflated the tire (tubules) and held for 2 days until I went to the vulcanizer for repair. Courier with Daytona cargo

I never managed to screw the end of the valve on.... I even went to a vulcanizer for help and even the guy there couldn't screw it on with gloves, resulting in almost all the foam coming out.

Simply removed all the foam from the hole that the tire had.....the hole was not big, it had been caused by a screw

Perfect product! I have used it 2 times. The first time I got a flat tire and used it, I continued to use the machine almost all day and it didn't deflate. However, the next day, in the morning, the tire was flat again. I had to follow the instructions and fix it then.

Tip: Shake the container very well before use. Place the valve of the pump high and vertically towards the ground. Screw the hose, keep the bottle vertical and press continuously until the tire is completely inflated.
