For my mom she’s 96 years old and I don’t want her to use real candlesI do not give over 4 on a good product. These are great replacements for my little jar that flickers that my once girlfriend gave me. I use it during the holidays so they coming in a multi pack will last me for a very long time. I am so glad to have them as I need them for such a long time. they came quickly and safely. I hope your business continues for many years. I just might need such an item again. lolMy only issue was with the brightness, but they are tealights, and it's been so long since I used a "real" tealight that my expectations may be a little off. Overall, satisfied!I use the in my diorama with blast affects around one so it looks like a bigger camp fire. They do last a long time. Not sure exactly how long but I would say a few days or more if you just left it on constantly. I would buys these again. Thanks for a great product.They did what I was looking for which was lighting a carved pumpkin. All of them worked and provided a nice realistic flame effect. I took off 1 star due to the description stated they lasted 100 hours, it was half that.Easy to use , no need to worry about fire hazards, adds perfect touch to decorate indoors. Cannot be used for bright light effect.There were no instructions to explain how to use the timer or change the battery.Just three or four will cast an 11×13 room in a dim, flickering light perfect for watching horror movies or telling scary stories. You won't be able to read a book (unless you're holding the book in one hand and one of these lights in the other; I was pleasantly surprised how much light they give off at close range), but with three strategically placed lights I was able to easily get around a cluttered room without bumping into or tripping over anything during a late night blackout. Love these!
