Bests & Worsts Reviews from Amazon

Worked just as advertised at first, behaved just as it should following package directions. We have a long, narrow bathroom, with blackout shades on the windows and a separate room for the toilet. At first I loved how it would detect my movement from about 7 feet away as soon as one entered the bathroom and it would light the rest of the way to the "toilet room" so it didn't require turning on the uber-bright bathroom lights to get to the toilet room (which are visible from the bedroom and sometimes annoys a sleeping spouse.) The green color was perfect for our bathroom colors (even though when the bowl light comes on it doesn't light up enough for you to see the rest of the bathroom decor). I got curious what the "carousel" colors looked like, I'm not a fan. The red looks like a bowl full of blood, the yellow like a bowl of pee, so I wanted to go back to the green only. Chose the green, as per directions, didn't get the flashing light showing it was activated. However, it did seem to work, it came on when it detected motion... and it stayed on. Only way to get it to turn off if to turn on a light, but when it goes dark again the device turns right back on and stays on. And it's not motion, I can go into the bedroom and see in the bathroom mirrors it is staying on. I left it for an hour... still on. Tried changing colors, taking out batteries, putting them back in, going back to carousel mode... nothing seems to work to get it to go back to working how it should. The motion detector works to turn it on initially after choossing the color, but whatever is supposed to detect motion now no longer turns the device off when there is no more motion. Edit: Two days later, after tinkering with this thing and the buttons for a long time yesterday hoping to make it work as it did before (no go... It still turns on and stays on (motion detection no longer turns off after 45 seconds like it did before, as its supposed to, but now even several hours after no motion it stays on) I was curious to see if my review had been posted on Amazon. What is up with all the recent reviews after mine 2 days ago that say they got the product free for an honest unbiased review? Am I the only person in the past few days who actually was a sucker enough to pay for this product? Are all those good reviews after mine fake because they all seemed to like the product but have the disclaimer saying they got it free... Are these people for real (Did they really try the product or just give it a good review because giving high reviews makes them more likely to get more freebies later?) Maybe the people getting the free ones are getting theirs from a good lot and not like the lemons that I, and several other one-star reviewers, paid for. Edit: talked to a friend about the whole high ratings/ disclaimer for "honest reviews" .... Found out there are websites where you can get goodies offered on Amazon for free or at a discount if you review the item and include such a disclaimer that you you "honestly reviewed" the item and send a link to that review after it has been posted on Amazon to prove you reviewed it and included that disclaimer. The more reviews you post the more/better offers you get but people also say if you always give out 5 star reviews you'll get many more offers and get fewer if you give any low star reviews. And taking a quick peek at the people who reviewed this product with 5 stars around the time I got this lemon of a product ... Many of these reviewers you can see all the products they review are for free or at a discount and everything they reviewed got 5 stars. These orders come up as Amazon-Verified but often they got the items free or a 99% discount and paid pennies for it (plus shipping charges, but no shipping charges for Prime members). I wish Amazon would separate these reviews from those that actually paid full price for the item.... This is something I'll now be on the alert for with future purchases.
