Query: Absolute Meltdown

Royal Sovereign ARP-1003E Portable Air Conditioner 10,000 BTUThis is one of the worst items offered through Amazon - and one of the few I've returned. It's noisier than a busted muffler, shuts off every half-hour when the tiny, tiny water container fills up - and gives you no way to easily empty out the collected water. If that's not bad enough, it also does a very poor job of cooling a small room - and it's a cumbersome pig that weighs a good 60 pounds more than its advertised 20-pound weight. Terrible appliance.
