First, the nightlight feature is pretty cool. The light isn’t too bright and it has an off, on, or sensor mode which automatically turns on when there isn’t much lighting. This unit plugs into an AC socket and is unfortunately somewhat bulky, but you can plug in something else if it’s on the slim side of plugs. This unit does have a two prong outlet on it which may help nullify its bulkiness.
I happened to have purchased two of these units. One in black and one in white – although I’m not sure if the color makes a difference in manufactured lots or not. The black unit would emit a terrifyingly annoying sound whenever it emits the ‘ultrasonic’ soundwave… not very ‘ultra’… The white unit on the other hand, was not audible (to me). My kids all said they could hear a high pitched ‘scream’ – but only when in the same room.
Why is this a “Triple Protection” repellent? On top of the ultrasonic pulses, this also has an electromagnetic repeller and an ionizer.
Electromagnetic repellent? What’s this? This mode supposedly sends electromagnetic vibrations throughout your house electrical wiring, sending critters scrambling away. Because of this, the instructions note that there may be an increase of pests for the first two weeks as they are fleeing the premises.
The ionizer supposedly does what it sounds like… it purifies the air making the air less pleasing for “dirty” bugs that like a dirtier environment.
Has it worked? no… I haven’t noticed any big difference in amount of bugs. There have been a few come around in the same numbers as they have before. I am curious to see if it does anything when it warms up and the bugs really come out. Below freezing temps haven’t really allowed optimal testing, but I do plan on putting this outside (for indoor use only) on the front porch where it’s protected from the elements. With a 5000 sq. ft range, I’d love to see if those box elder bugs stick around on the trees out front!
-Stay tuned- I will revisit this subject in the Spring time!
