How accurate is this? Has anyone done some solid tests, measurements monthly vs bill? I'm only interested in tests you have validated as VERY accurate

I've been using it side by side with a digital usage meter provided by my utility company (SMUD) and it is always within 30 Watts (shows 30W less). Not a scientific test though :).

I find the scale to be accurate. Hard to say if it is accurate to the oz level. It usually matches my good scale at home. I travel with the portable scale to help maintain my weight on long business trips

I don't know how much you have been involved in "accurate measurement,?"They have been doing this to our propertyfor quite a while.Your measure is going to be more close, I promise you!

It was not very Accurate. Also... my third purchase was a bad unit. Neither the seller nor the maker would respond... not even to the BBB. Be careful. The working two have lost most battery life after a year. Good luck.

Yes I suggest you try a side by side test to make sure. You can contact their website with questions. I believe they make a meter also.

Sure, I am in Massachusetts, where it is quite humid in the summer. I use it throughout the summer, almost everyday for at least 12 hours, sometimes more if I am working from home. I would say the its adds about $30.00 a month to my bill during the summer.

Hi Paul, $14.95 is the basic monthly fee from 5*, but my actual monthly fee was about $18 with taxes. Recently, I added insurance on my 5* unit since I tend to be clumsy, so now my total monthly cost (with my state's taxes) is a few cents over $21. It's more than worth it to me. 5* has so many services. I wear mine all the time and I have felt safe ever since I got it. Even at $21 it's well below the monthly cost of units offered by other companies. 5* responds immediately and professionally. The unit is well made and I expect it to last a long time - I've had mine for several months, expect it to do well for years. Hope this helps in your decision-making.

It's pretty accurate. Did a test at my doctors office and at a pharmacy store and they were all right there with almost the same results.

I don't know because our electric bill is budgeted out by the month, so unless I take the bill before we bought the unit and the bill afterward to check the units used I wouldn't know. Sorry

I had that scale for a few weeks only. It never worked properly, I tried on different surfaces around the apartment. It would show different numbers every time I weighed myself and it went dead in about a month. It's not reliable, so you can't really trust what the scale shows.

Hello, I've had mine for a little over a year and feel it's a good tool for the household electrical measurements. I started out measuring my fridge, washer & dryer, computers etc;. My main concern was the lighting in the house. At about 6 months I was getting a pretty good idea that this was a valuable tool for me. It was this tool that convinced me to change the way we do laundry with how much clothing to wash and dry at on time. Also changed to LED's for lighting. The Belkin wised me up to the coffee maker using power when not in use. At about 12 months I realized a 41% decrease in my electric bill. Accurate, I think so. Especially when your on a fixed income like me. I hope this helps you. Thank you. Dave

Not many tests exist that are 100% accurate under any circumstance and this is no exception. Though through personal experience they have been accurate both when I thought I would be clean and also when I knew I wasnt. And like many others here. Take 2 back to back and compare results. Dont worry about the shade of the line, that doesnt matter...what matters is if its there or not. And this tests states that it tests up to 50...not 75 like another reponder.

I have found mine to be very accurate. Perhaps you did get a defective one and should ask for it to be replaced.

Hello Nick, what are you using it for? I am using it for the pool and it is very accurate, but you do have to convert it from Parts Per Thousands to Parts Per million, so it will appear very low on the meter. Bob

The electrical bill actually very low. I set an automatic temp at 68-70 degree every night prior I went to bed. It kept the house reasonable warm until I get up the the morning. It ran like that for the entire month and my electric bill still lower than let the house heating unit run all night. During the day I raise the tempt to about 75 degree or set it 65 if everyone at work. Overall I save about $20+ per month in electric bill last winter. Beside functionality, the electric flame makes the house more welcoming. I don't have any complain about the heater. If it's on sale, I would buy another one for upstairs.

Daniel. weve got 3 of them in our house and I can honestly say our electric bill hasnt changed significantly. What doesnt seem right is the filters are so darn expensive than if your house has allot floating in the air the filters dont last 3 months.

Thanks very much for the response. After entering my question, I figured out how to fake it myself with what I've got. I just put the cost of electricity at 1.00 per kWh. So now after any amount of time, instead of it telling me how much money I've used each month/year, etc... I just read how many kWh I've used each time period. Sometimes you have to be smarter than the $20 device, but it isn't always easy. :)
