I bought two of these tire repair kits to put one in each vehicle. I also bought two new jacks for each vehicle. Generally them jacks that come with your vehicle aren’t no good anyways. I had a flat tire way out in the country and I couldn’t get my tire off, with that cheap wrench. I couldn’t get the car jacked up anyways. left me stranded. Not anymore I got two new four-way lug wrenches two new jacks and a tire, patch kit, and two of them little air compressors that you hook up to your cigarette lighter..

Amazon sell a fine selection of replacement fiberized rubber fiber plugs & cement. Read the reviews.

Color: Vivid Orange

This is the only kit you will ever need at roadside to plug a tire & be on your way. This kit has it all. I'm a retired long haul trucker. This is my preferred plug kit. I have stored one of these in all of my trucks & my wife's SUV. You could spend so much more for other plug kits. But this one works. The price reflects the quality of both the tools & all the other essentials you will ever need. I recommend you buy this one. The money you save can be used elsewhere. Note: Amazon sell a fine selection of replacement fiberized rubber plugs & rubber cement. This is where you don't want to skimp on cheap-O plugs elsewhere. These two items are the most important items in the entire system. Be prepared! Always read the reviews & know the sellers reputation before you purchase things. ///////////////

ALMOST perfect.

Color: Vivid Orange

Item is as advertised. Durable, and the tools are useful for more than just regular plugs. It comes with the snips which was great as well as actual valve stem replacements which I thought were pretty nice. Only complaint are the plug strips themselves. If the hole is from a bolt or something larger than the average screw, it may take two of them to completely stop the leak. Hope this helped.
