I bought this product because the handles are T instead of being in the shape of a screwdriver. To do the job it's more convenient and easier to handle. The tire was repaired in less than 5 minutes, and more than 6 months after the tire has never lost air. I recommend. The pressure gauge is imperial, too bad, but just do the conversion once and remember the value. I just know that between 33 and 36psi, I'm good.
