Its two years since I purchased this and happened upon this link today. I remember doing a great amount of research when I bought this unit. It is NOT like the one being reviewed with 2 stars.

One key point - it has two hoses - input and output (not one like many units out there). It's very good at evaporating the water it takes out of the room (the two hoses are supposedly responsible for this efficiency). I have yet to empty the tank. The unit comes with a window package that holds the tubes in place (its made of heavy duty plastic).

As to moving it around, no big problems - it is a beast to move on the stairs, but ..... its an air conditioner, not a fan.

I normally use it to cool down a 20x20 room (9 foot ceilings). It does take longer than I'd like, but if it's a humid night, it gets the room in a "sleepable" condition in about 1 hour.

I bought this AC after reading the 2 star review and I am very glad I did. I live in the college dorms and this AC does an excellent job cooling my room and I have not experienced any of the concerns posted by the other reviewer. I've got a few other friends with Portable A/C units and none work as well as this one.

The wheels roll fine on the dorm room carpet, I've had this A/C for over a month and have yet to empty the water tank, and this A/C gets my room as cold as I could ever want it, and could get it even colder if I so desired.

I got this unit on sale for ~$230 and this has been a great investment.

Price is good, Delivery was good, After 2 weeks of use--the unit is running very good so-far.
The best part about the unit is---it's the only model/company that has an AC that will turn itself back on after a power-outage!!
Here in Los Angeles, we have many power outages every summer.
I looked high and low and the SPT is the only unit offering this feature.

Plus***the sales dept./salesman, Mr. Wyn at SPT is VERY helpful, extremely knowledgable and customer satisfaction oriented.

I give their customer service/sales an A++, and their AC unit an A+.

Enjoy
