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

Ying: They arrived as promised and seem to be working well. They fill my need for an adapter. Yankee: Not really. (I will neither confirm nor deny that it is copper or a copper alloy. Before receiving it I was skeptical as to whether it was aluminum or zinc. However, they seem too heavy to consider a less dense metal be.)
