I have one. Don't even consider buying one that has only an exhaust vent hose and not a separate intake vent hose, because these will create an air vacuum in the room it's in and consequently suck air from leaks around doors and windows, other rooms of the house, and such to replace the air it's constantly exhausting. You'll feel cold air blowing from the portable A/C, and yet it will usually feel too hot in the rest of the room when you're not right in front of it. The dual-hose portable A/Cs avoid this problem by cooling *outdoor* air and thus bringing new, fresh air into the room to replace the air it exhausts. Also note that cheaper ones require emptying a bucket of water every few days (every day during the hottest and most humid times) unless you have a nearby drain. Better units have an internal pump to allow you to drain water upwards (i.e. to a sink or out the window), or better yet, have a self-evaporating feature that exhausts evaporated water out the window with the air. I use mine only because it's difficult to mount a window A/C in a side-hinged window that swings open. Although a panel to hold the vent hose in your window is usually included, these almost never fit any real window you'd use a portable A/C with; I've had to fabricate my own panel every place I've ever used a portable A/C. Mine (an old one I think was manufacturered by Fedders and private-labelled as Home Depot's house brand) also tends to leak or freeze over. I'm not sure why this sometimes happens. It gives you an option to self-evaporate, but the coils freeze over even more often if I use it, so I stick with draining into a bucket.

I buy the 12" American Bully Sticks from BestBullysticks.com. BESTbullysticks.com is the place, better prices and better sticks. They usually cost me about $57 delivered for 25 of them. This is for our Chihuahua which is a voracious chewer. One will last her anywhere from 2-6 days. Here is a link that might be useful: Best Bully Sticks

I know that in New York this would be typical because you have lawyers involved. If attorneys are involved in Massachusetts, my guess is it's the same dynamic. In other states where realtors are allowed to use a boilerplate purchase agreement it's immediate upon signing of all parties. So, it differs from state to state. If you have lawyers, all that you can do is try to light a fire under them. I ended up living in a residence hotel with three large dogs in the middle of a New England winter because my situation didn't seem to be of importance to anyone other than myself. You want to hurry them along, too. Another buyer/seller may make a better offer. It happens. It happened to me. Fortunately, it was to my benefit.

We gave our Roomba away - the cons outweighed the pros. The dust bin is very small and if you have a hairy dog it fills up very quickly. It sucked up the fringe on my rugs and after untangling the vacuum from the fringe the fringe was shredded and several threads had broken off. It worked better on short fringe. It did a decent job of picking up surface dirt from carpets but it isn't a substitute for regular deep vacuuming. It was fine on ceramic tile. The suction isn't very strong and it was unable to pick up dirt when one wheel was slightly elevated on an area rug and the other wheel on the tile. It was very noisy. I used to put it in a bedroom and shut the door and let it run - it was low enough to go underneath the bed and get the dust bunnies.
