Review on Blovess Yueton 10pcs Copper Presta to Schrader Converter: Car Valve Adapter for Bike Tube Pump & Air Compressor Tools by Corey Slivinsky

Great product for the money. Worked great. Just remember to unscrew the presta valve before screwing it back in. I didn't leave it on the valve as I only need to use it intermittently with the electric compressor. A small issue was that there were only 9 pieces in the pack which were cut with a razor. This could easily have happened when opening the original packaging. But I only needed one so I have 8 more of what I need.
