The sensor is a light sensor, not a motion sensor. The unit sprays way too often. Everytime the light level in the room changes the unit sprays. Anything can set it off, from a shadow crossing the sensor, turning on a light in the room, turning off a light in the room, opening a curtain in the room, closing a curtain in the room, or turning on a TV or computer monitor in the room. Again it senses a change in the light level, not motion. Sometimes it even goes off on it's own with no perceptible change in light levels in the room. Maybe a cloud passes by outsides and casts a shadow just right. It should not be advertised as a motion sensor.

yhis looks nice in any room in the house!!! the aroma it releases lasts a long time filling the room with a fresh scent!!! some areas in my home are big and this spray covers the larger rooms perfectly!!! i love this!!!!

I did not like this one at all. I have tried the Air Wick ones and assumed that this would be the same but I was extremely disappointed with it. I don't intend to purchase this again

No thanks....this stuff is so strong and very synthetic smelling. I also didn't like the way it shot out the spray randomly. I wouldn't repurchase, we brought it in the garage as to not throw away.

I didn't like this product at all. Sometimes it would work and other times it wouldn't.

I strongly dislike the Sense and Spray model. I know several people who use these and I just cannot understand why. Here is my question - why would you want a scent product to spray a jet stream of scent at you every time you walk by - and heaven forbid the home you are visiting is full of tall people so they set the contraption at eye level for you BAM right in the eye. Not a pleasant feeling and not a good product.

I love these, I have 3 of them. I especially love the fall scents when they are available. The scent last a long time.

I love these. I have one in bathroom and in dining/living room. Works perfect and love the smell. I really like that it only sprays when you walk by it. Wish they were a bit bigger though. I even have company ask 'what's that smell? I gotta get one"

I'm sorry I can't stand this little contraption! It got on my nerves so bad, I wanted to throw it out the window. It sprayed the tops of my wooden tables and stained them. Luckily, I found a way to get it off. Plus, every time you walk by the blasted thing-swish swish. It actually sprayed the mist on you. Needless to say, that thing is history!!

I liked this at first. Although I'm not a fan of the sound it makes, I do like how it doesn't waste the scent when no one is around. However, mine has now got a mind of it's own. It just continuously keeps spraying. The only way to stop it is to remove the battery. I'm not sure if it's just mine, or they do this after time.
