Since my new car, unfortunately, has only an uncertain shelf for drinks in the glove compartment I ordered this drink holder. The delivery arrived quickly, but without the specified screws for fastening, this would have been forwarded to me as soon as possible but free. But since I had enough screws in stock I built the cup holder a equal. As long as the drinks have the approximate size of the holder in zeroing everything is good. However, you need both hands to adjust the size if you will, for example, put it back a 1.5L bottle. Then take out the bottle of the holder returns to zero so that you again need both hands around the bottle to put back into it. So really only suitable for 1/2 liter bottles and cans! Folded it considers, however, and does not work on its own again and also acts otherwise quite stable!
