I keep this cooler in the trunk of my Audi A4, which isn't a very large trunk, and I use it primarily when I travel.  I take it out and into the house when we need an extra cooler for parties with lots of guests.  My wife thinks it "whines" but I think all coolers of this design do something like that and, after awhile, I don't hear it.  I take it into motel rooms with me when I travel and use the AC adapter, and it has operated flawlessly.  It is designed to fit into small spaces, like the footwell in the back seat of a car, so it's understandably a low volume cooler.  I like that it has a carry handle.  The lid has no lock; it's just gravity that holds it down, but I don't find a problem with that.  To my ear, it makes a whirring sound that you'd expect from a small fan, and what matters is that the cooler keeps things delightfully cold and doesn't take up too much room in the vehicle when I travel.  I use it to sit on sometimes when car camping, but I wouldn't want to stand on it.  It is what it looks like, and mine meets my expectations entirely.
