Good value for money. Takes some getting used to.
This device was simple to use and it held up air well while providing some traction. It takes a little tweaking and getting used to to pump it to enough pressure. It uses a plastic ball as a valve and after a few pumps, it was difficult to get it to inflate to the right pressure. The air kept leaking back through the pipe. I had to pinch the pipe after each pump to prevent the leakage for the last few pumps.
