what size room does it facilitate, how long is the chord, does it have a tester or on off indicator light. Will it bounce off walls or window in a apt, what are the dimensions

Negative ions don't have a very long life span, they come out looking for something to attach to. There really isn't a facilitating room size. You can maximize your results by putting it high up giving them more space to fall through, I have my on top of a box on top of a wardrobe so they have plenty of room to fall. Its also suggested if you are using it for sleep you have it about 3' from you. Negative ions don't bounce, if they do travel to a wall or window they can leave the legendary black spot, essentially they take anything they have attached to and stick to positively charged surface. However this unit doesn't have a fan so they don't blow across the room and make a black spot. The cord is a good 8'. Is roughly 4" x 6" and 2" high. It has a "tester" but it only tests that its working. There is no on/off, if it is plugged in its on.

I'm going to buy a bigger one. It's not as good as I had hoped, especially with thick walls and electrical outlets, wires, etc. nearby. I guess it depends on your layout, distrance involved and so forth.

It works great in an apartment/house. I got it for hanging up pictures, curtains, decorations, etc around my house and it worked amazingly. It's fairly small so it's easy to store. Also, it's usable right out of the box since it doesn't need batteries or to be calibrated. Hope that helps!

Yeah, it's basically just an extension chord mounted behind the wall. It works great for TV's because the 2" circular outlet is hidden behind the tv and you can run other chords along with it, whereas this might be an eyesore next to a tiny speaker. I don't think you can just run the chord for your Sonos behind the wall, so this might be the best solution. It's really just the novice DIY way of putting an electrical outlet up in a place where you don't have one.

My unit is mounted at about 9' off the floor in room with 10' ceilings and it detected a CO build up in the middle of the night that could have easily saved our lives. We live in the middle of the forest and during a power outage our back up generators exhaust came into our bedroom through a slightly open window.

It works for us in a 2000 square foot home with two levels. There are couple of drop spots. Inside the bathroom closet, one spot at my office, but otherwise, it is quite good. You need to make sure the inside antennae is at least 8' from the box, and the outside antennae needs to be 25' from the inside box. It's quite good, and we are happy with it!

1) The lights in this deal (not available atm) are just over 48" long.2) The blues and the whites are on different power cords, there is NO switch for either though. This should not be considered a negative. For around $5 you can buy a decent wall plug timer at any walmart (or here on amazon?) so you can turn them on and off at different times.short answer: 1)48" 2)Yes

This effect covers a very large area. I velcro it on top of one of my speakers and it covers a 40' X 30' room. One should be enough unless you're at a huge club. It's pretty awesome considering it's size.

I use this only in my bedroom at night. I turn it on an hour before I plan on going to bed and close the bedroom door. I can tell a definite difference between rooms. My bedroom is about 10x12. This is not a unit for a whole house or for rooms that can't be closed off (in my opinion).

I used the unit in my sofa and arm chair, but to answer your question, it seems to reach just about anywhere. I would rotate it up above me while I was laying down on the couch, and it worked perfect. I think the reach would be up around 2 feet from the side of your bed. Bare in mind, that the unit has to be right beside your bed, and I found that it was in the way when I jumped out of bed. I had it positioned it above me when I was watching TV and to the side when I was in my arm chair. The unit is well built and worth the investment. I hope this answers your question. I have it my house in Arizona, but I am going to buy another one with spring for my house up north.

When placed in the middle of an 8 foot wall, it easily shines on the ceiling and floor. I bought the unit for outdoor karaoke parties, placing the unit on the side of a 15 foot wall, but haven't had the chance for a party yet due to the weather. I have had the unit on continuously for 3 or 4 hrs. Great buy!

suggest to use it in a small closed room, not larger then 180sq feet (8'h). 2times of 15 min.

It's designed for indoor use since the ultrasonic feature works when the sound bounces off the indoor walls. All the best ... Jeffrey A. (Jeff)

Wall unit is 4" long, 2" wide and 1 3/8" deep. It has two keyhole mounting holes for wall mounting or 3M type Command Strips can be used. Be have a cabinet by the back door, so it just sits on a shelf. It has a short antenna wire and a power supply wire (both small guage). Our unit works flawlessly. Well worth the price.

The chord is a plug in, clear and coiled so if you have a short distance, 8", or less, it hangs tight. If you need to go a greater distance it will stretch. Nice feature.

If you need real specific tests I can measure for you, but I've used it from one room, through a wall to the next room, back when I used to have my desktop wired to the TV. I'm just heading that was a solid 8'. But throw in the wall and I was impressed. I can measure though, but I'm sure it'd reach 15', unobstructed.

it's only about 10'. I have it plugged in and hung from the center of the room cord run up the wall.
