Not what ad picture promotes - just patches - no more
Size: 24 x 35mm
For twice amount of money that other tire kit repair offer - it has no glue, no lighter fluid, no scratch tool - just top $ for patches. Show in video how to fix, but after you get it you'll find that you need to go back online and order, glue, lighter fluid, scratch pad, and perhaps even a roller tool. Just order a kit with needed accessories & patches to start with at half the price.

Rectangle shape covers & adheres well.
Size: 24 x 35mm
This is a rectangle shaped patch that I prefer over circular patches. Covers well and gives new life to inner tubes on the used bicycles I repair to give to charities.

Just the patch, nothing else
Size: 24 x 35mm, Size: 24 x 35mm
Tried this with cement glue for PVC piping. Not sure if they are a different type of glue. The patch didn't stick at all. The instruction says to use lighter fluid, which I didn't have. Very inconvenient to need all sort of stuff to just patch a few dollar tube. I was hoping a simple process of removing the cover and sticking it on the tube. Several hours of waisted time.

Amazing kit, it has everything you need!
I never really thought about keeping a tire repair kit in my car, until I had a flat in the middle of nowhere. That’s when I got this 54-piece Flat Tire Repair Kit with Air Compressor, and now I wouldn’t travel without it.
The kit has everything you need to patch up a flat quickly and get back on the road, and it’s surprisingly easy to use, even for someone like me who’s never done it before. The air compressor works fast, inflating my tire in just a few minutes, and the tools feel solid and well-made. Value for the money: 10/10
Honestly, this little kit (amazing size) saved me from a stressful situation, and now I tell everyone: just keep one in your car, you never know when you’ll need it!
