Great product!
Size: 36 pcs
This is great, it cost $10 at a shop to get a nail removed and plugged up, this cost less than 3 trips. It is especially helpful when you live in a high construction area like I do. Easy to use comes with everything you need. Great product and great price too.

Easy to use
Size: 36 pcs
Great quality. Worked great on first try. Pulled out a sheet metal screw from my work van tire, reamed it out with the tool, inserted the plug and pulled it out first try. Tire is holding air perfectly. I would definitely recommend this kit for anyone whondoesnt mind plugging a hole in their own tire.

Good, but far from pro grade
Size: 36 pcs
It’s a good to carry on the back of your rig product, but one can tell it’s a made in china quality deal and would not hold up to full time working duty. For the price it’s a ok deal

Quick and easy solution tire kit
Size: 36 pcs
This tire repair kit has been great to keep in my EV9, Model 3, Model Y, and Lexus RX for emergencies. The tools feel strong and durable, and it gives me peace of mind during road trips and daily driving. I’m very thankful I had this kit because you will never know something or someone may puncture a hole in your tire! Especially living in California! Saves time and money on specially if you’re out far from home and no time to wait for a tow truck.
