Not good. Do not buy.
I ordered 3 pairs of 1.75. Received 1 pair 1.75 and 2 pair 2.0.<br />Good think I also ordered an eyeglass tool kit for $8. The tool kit worth every penny. Because one day I had to tighten the screws and nuts on one pair and after 3 days a second pair would not close. I had to use the tool kit to fix the frozen arm.<br />I knew they were cheap and I knew I would have to tighten up the screws and nuts once in awhile. But the first week have two pairs go bad.  I haven't worn the 3rd pair yet. I would not buy these.
