Query: Ok but not very good

The quality of this product is OK. I'm looking for one with metal cap, but it's plastic, it looks like metal, but it's plastic coated with a metal paint. Before I bought it, I called the seller, they told me the cap is metal, it seems they don't know anything. The plastic cap is easy to be broken in the winter, I can get it in any hardware store at lower price.
