First delivery was slow in coming. The money was debited immediately after the order. What an ever had a bad feeling aroused in me. Today, the set has arrived undamaged at me. I had ordered exclusively for the Schrader valve adapter as my Fahrarrad unfortunately car valves. The adapter fits perfectly on the car valve. Unfortunately, the integrated non-return valve is not working and the tire was quickly floored. So I sat on the bicycle pump, trying to get air in the tires. Just as I was pumping the pure air, so this entweichte again. Absolute botch and not recommended for car valves. Since the price was low, I did not make any complaint. Since it would not justify the cost and effort.
