I put it on a wheel with a tube from a construction cart. It has stopped losing air now and seems to hold up.

I used two 300ml packages on a 215 65 17 tire. I immediately added air after, but it continued to leak from the hole. I left it lifted with a jack to prevent the tire from getting damaged, and the next day I added air again and it had sealed. If I wasn't at home during the process, but on a trip, I believe I would have had transportation issues. I should note that I had removed the screw from the tire

It looks very high quality for the intended job, much more affordable for those who have used the one provided with the car (-70%). Fortunately, I haven't had the chance to use it yet.
