Review on Delta Cycle Expanding Beverage Holder: Ultimate Bike Cup Holder for Water Bottles, Coffee Cups, and More - Enhanced Grip and Easy Installation - Durable Construction by Payton Luna

So this doesn't work on my bars which have bumps and corners as the only real voids for a cup holder. It lacks adjustable articulation points to get a perfect angle. If you have a completely horizontal position on your bars, it's not too bad. Slightly flimsy feel but could hold a beer, small bottle or coffee. But it's very limited to that specific use. I'll keep it, maybe it will fit in different bars in the future, or I'll pass it on to someone who can use it. Not a big loss since it's so cheap.
