It worked fine on the first day of my ownership, I don't see any problems with it in the near future. However, when it comes to material and build quality, there is no bottom rung on the ladder in my opinion. So if you spend more than $5 for a branded adapter (Chinese) instead of the $0.99 unbranded version, prepare to be disappointed, as I was. If I ever bought a bike pump and found that it incorporated the same part as their permanent quick release skewer, you would have a hard time gifting me that pump. Another warning: This product contains lead.
