One of the worst purchases I have ever made in my life. 1 star is too much. Supposedly the hose can withstand 2MPa (about 20 bar). In the first inflation with 6-7 bar, it punctured after 1 minute on its own, without even using the air gun. I patched it up as best as I could and in the second inflation a new hole opened a few centimeters away. In the third inflation, a third hole appeared a little further away. In the fourth inflation (now with fewer bars, around 4-5) a fourth hole opened 5-10 meters away, in a completely random spot! In the fifth inflation, a FIFTH hole opened, again meters away from the previous ones. 5 holes in 5 inflations, without even reaching the operating limits of the hose (after all, my compressor has a limit of 8 bar). I have now stopped the tests and will try to convince the seller that the product is defective.
The quick connector leaks air if the gun is moved even slightly. It is not a problem with the gun, as I have tested it with 3-4 other hoses and had no issues. Only with my Yato it happened.
Do yourself a favor and stay away from this product.
