I had great luck with this product. It was purchased for me as a gift for Christmas 2023. I've the jumper cables twice and they are very high quality and have worked great. I just now ended up needing to use the flat tire kit in October 2024. My 2018 Jeep Wrangler Tire was flat in my driveway. I shook the sealant for about 20 seconds and connected the sealant to the tire, then the inflator to the sealant as instructed in the manual. I let it run for 12 minutes as suggested. I turned off the inflator to allow it to cool and also disconnected the sealant at that point as I figured it had all been pushed into the tire, since air was making its way through now. I moved the vehicle back and forth a couple of feet to allow the sealant to spread through the tire and seal the leak. Then I reconnected the inflator to check the pressure, which was a 25 PSI. After letting the inflator cool for 20 minutes I came back topped off the tire. Without the sealant bottle attached, the inflator worked much faster to top off the tire. I actually drove for 3 days (all local 15MPH-40MPH travel) before getting the tire repaired, and it held the pressure the whole time. The tire repair tech thanked me for not using "too much Slime" in the tire and keeping the clean up to a minimum. I told him I used a kit that had the right amount determined for me. I was kind of shocked to see the other reviews when I had such a good experience. I could see getting frustrated if I am on the side of the road and maybe I have to let the inflator cool for a few minutes before topping off, but it's still better than waiting hours for a tow truck or tire service. I recommend the product and suggest reading through the instructions before having to use it for the first time.

Useless!! On interstate 40 or Chapman Highway, watch out you’ll be run over by a car before the tire is full of air or much less if you have to patch it!!!

Seriously, you don't want this. I only needed to put 3# of pressure in a car tire and it was SMOKING before it finished. This would be USELESS in an emergency situation, especially if you were in a truck or any heavy vehicle and your tire was really flat. It's SLOW and you can only run it 12 min before it overheats; then it has to cool down for about 20 minutes. Again, it couldn't even put 3# in a Challenger car tire. Ladies - and this is coming from a woman- don't buy this thinking it would be helpful in an emergency. Men, don't buy this thinking it might help your wife or daughter out on some dark road. It's false security, and I think that's what makes me the angriest.
