I used one box of 6 Wednesday. They are easy to set up. I place chair in the middle of rooms to be treated. They provide 2000 cu. ft. For each can, one box does 12000 cu. ft. My home is 1500sq. ft. That a little over 6 cans.

I purchased three of these.  They are extremely easy to use!  The directions were little unclear but it was still very easy to set them up.

Pros: Cheaper than most sets, easy to set up
Cons: Just a few, see below

I set these up in my bonus room over the weekend. Overall the experience was pretty good. Setting them up was a breeze, and took me roughly 5 mins to unpack all 4 and have them ready to go. Depending on your speaker type and how you want to mount them, the included screws may not be enough for you. For instance, I have the Onkyo SKx-670 bookshelf speakers. I wanted to mount them using the screw-hole on the back. The included hardware didn't have the appropriate screw size so I had to run down to a home improvement store to pick them up (only $1 for these screws so I'm not upset about that).

One issue I had when setting the height was that I broke one of the collars that you tighten down to hold the position. Now I will admit that I more than likely over tightened it, but I thought I would include that warning here so others don't.

The only other issue that I had was that after installing the speakers, they have a slight tilt due to being top heavy. Now my speakers are only 2-2.5lbs (depending on whether fronts/center/surround) so about half of the max rated weight. Now I read the reviews and figured I might run into this so I won't be too mad. The tilt really isn't that bad (maybe a 5* angle) and I have the stands at 40", so almost at the max height. One thing I found to help minimize this is to turn the speaker to that it is pointing in the direction of one of the foots of the base. This seems to help out some. Note that I am also on the newer shag-like carpet with 10lb padding so that could be another factor. The angle isn't bad enough for me to even want to think about sending it back, but be warned that if you have speakers nearing that 4lb mark, be prepared to make modifications or set them really low. In the next few weeks I plan to figure a way to add some weight to the bases to reduce the angle.

Overall I'm very happy with the purchase. Shipping was fast (got to me about 3 days before original esitmate). I used 14AWG wire due to some longer runs and there was plenty of room in the stands for the wire. I would venture to say that you could even use 12AWG with no issues.

I have only had the cameras for a week, however they setup in minutes and are easy to use .. Some lag in capturing video, as well as pixelation when switching from IR to color, but overall satisfied for the price paid

This is my second order.  I like that there are easy to set up.  I don't like that they don't last as long as I would like them to.

These are easy to set up. I bought several sets to hook together to give our chickens (adults with clipped wings) a chance to explore different parts of our very large yard. We easily just pick it up at one end and start folding back and forth until it's flat and take it somewhere else. The design is good, I worry, though, about the stoutness of the "pins' for lack of a better word. It seems they bend to easily. If I'm not too rough on them, here's no problem, overall, a good product and will recommend
