Great in every way
Nice kit full of useful tools to fix punctures in tires better than anything I have ever tried before. The quality is pretty good - good enough to do what it’s supposed to do. It’s better if you fix your tire when it’s off of your car. It’s a lot easier to push the plug down when your standing and can use your body weight rather than laying on the ground in an awkward position and trying to push the plug in. I did the latter and it was not fun. I lived and learned. Anyhow, I wasn’t going to drive on rims essentially with a flat to get it repaired somewhere so this was a fantastic buy.

Amazing
This was an amazing kit, I recent got a hug nail in my tire and wanted to save money. The directions are super easy to follow and actually doing the job was a breeze. I’m no mechanic so I fully recommend this product. Definitely cut down the unwanted rubber at the end.

Great Kit
This is a really nice tire repair kit. It contains all the parts you will need to fix a flat caused by a nail or screw. I would also recomend everyone keep a tire inflator in your vehicle. The kit is very compact and takes up very little room in the trunk.
