Stopwatt Reviews 

I Should Have Known Better.

This product does not work, and the additional items that they try to sell you during the checkout process are ridiculous. Having to click through and decline all the additional products at checkout should have made it clear that this is a scam product. I have had it plugged in for months, and there has been zero reduction in power usage shown on my bill. Stay away, do not buy. Just unplug devices before going to bed or use a power strip that will do it for you.

I disagree with the other reviews. My bill went down and I could not believe it worked. I have only had them for two months yet it appears to be working.
It was real hot in august amd my bill was under $200.00 when last year it was way over that.
Thank you.

Don't waste your money. Not one thing changed when I used the device for three months. I rate this as a scam.

SCAM if I've ever seen/heard of.
Listen to this long drawnout electricity video, as once again want you too buy something.
C-mon People get a Clue, If Something is that Good for Consumers, You wouldn't have to listen too a long/boring tactic video. They'd tell you in the beginning if this product was well known.
Okay said enough.
Save Your $$$ and put towards your next electric bill. 🤣😅

Attempted to place an order. My Stopwatt’s online order refused to process. Read customer reviews, appears as if Stopwatt has multiple issues!

I bought one put it near my fuse box then bought two more that made the difference one wasn't enough, I can definitely say they work lowered my electric bill big time , I'm gonna get two more

I have to admit. I fell for the BS. It's my own fault I didn't research further to see that the whole narrative about Kevin O'Leary is total fabrication. What I want to know is, how has he not sued these assholes into oblivion? I paid the hundred bucks. Got my 3 units. Just got my first electric bill since installing and yep, you guessed it, didn't do jackshit. That's ok. I can afford the $100 mistake but, someone needs to class action these scumbags into oblivion.

Absolutely garbage! The contact email is not a real email. The product does not work and there is no way to contact them, return the junk or get your money back! Scam!!!! Order #45E5EA19EC

You need to sell something that does what it suppose to. my Electric bill was more after I started using stopwatt. I guess I couldn't find anything better to spend my money that day. To make long story short it is just a piece of plastic with some electronics inside that the uses watts. Its just a piece of junk.

Stop watt won't lower your electric bill. Why? Because the power comes from your meter box to your panel. Your meter box measures kwh. It doesn't have a good/big capacitor in it. Best way to save power is to put up blackout curtains to keep uv rays out, keep the door shut, change all of your lights to led, unplug stuff not normally used and buy energy efficient products. Im a liscensed electrician and can tell you this is a scam!

Stop watt has a story about Kevin O"leary from Shark Tank investing, and after reaching his business manager, this is just an AI generated BS statement attempting to generate credibility. Also when ordering, the site is set up to sell 6 other bs products that will show up in your order for another 100 plus dollars. There is no credible proof to back the claims of 40.to 50% reduction of electric bills. This is a scam, in the 3 days it takes to post on my visa, i will dispute all charges. Dont waste your time or money on this scam!

Bought stopwatt electric Bill on was $47.05 lower what a RIP OFF didn't do as advertised.

The device simply does not work - made no difference in year-over-year electrical usage in terms of utility bills over nearly two billing cycles. Total scam. Should have know better. Asked for refund within 60-day window and it was supposedly sent - need to verify. Now need to sent units back at my expense. To not buy in the first place. Just Google "Is StopWatt a scam" for yourself - should have done so before buying.

A Pet Rock creates more value!
Kevin O’Leary obviously doesn’t care about his electric bill, he’s a billionaire, why would he care about ours?
What he cares about is increasing his wealth off consumers anyway he can, including endorsing fraud.
Protect what little we have folks, don’t buy into this scam.

I have not and will not purchase this device. The guarantee (per their advertement) states...you get a refund IF you don't save $1.00, read that, $1.00, on your electric bill. I then came to this site and see totally unsatisfied customers. Suprise Suprise! READ, LISTEN!!! SCAM!!!

Why would anyone give $$$ to this company or any company before vetting? A quick AI search instantly verifies the shark tank promo is a lie and the product and youtube reviews are a scam.

I ordered 1 device before I read reviews. Wish I hadnt ordered. The biggest ossue was when placing order for 1 decice at 49$ the site kept popping up with additional items to add. I skipped thought these continuing w origanal order or so I thought until I was shown bill for all additional items charged
No place to review order before I was charged. My bill was now 178$
I called the company right away and was given a whole run around w different options . I had to continue to insist I only ordered the 1 item and wanted them to reverse charges on the rest. They finally agreed. I will jave to wait and see if they follow through. . Buyer beware!!!

The people behind this/ these products should be prosecuted to the fullest extent of the law for fraud.
I ordered 1 item on their website, when I got to checkout there was 6 additional items in my checkout I didn't order.
I finally got it straightened out but it was a pain in the ass doing so.
On my online checking statement, each item was recurring. Meaning they were going to charge me for each item on a monthly basis.
I ended up having to close my checking account due to these criminals.
DO NOT DO BUSINESS WITH THESE CRIMINALS!!!

They should get the guy who is selling the power wash device that with a simple german engineered device can have the become a pressure washer. This guy should team up with the Stop Watt guy and have a baby then you’ll have something. Called a Stop washer. LOL

Does not work. Had it for over a year. Didn't save a dime.
