Twinkly Strings 600 LED RGB+White, LED Light String, in- and Outdoor Smart Multicolor LED Lights, Mappable LEDs, Compatible with Alexa, and Google Home, IP44, Black Wire, 157.5ft

I have been buying cheap, basically disposable, colored and white light strings for years. But when I saw these on my stepson's Xmas tree, I had to have them! His cost a small fortune just a few years ago, but these were on sale, just a bit above the cost of buying enough multiple sets to try to achieve the same effects. I bought the 400-led set (still on sale at the time of this review posting), which I found quite sufficient to light up my 7 1/2 ft. tree. I read some older negative reviews before buying - but seeing these in action (on my stepson's tree) sold me anyway...The lighted lenth is 105 ft., divided onto two strings connected by the power cord/transformer, This worked out great for me - I just put the transformer near the center of the tree and took one strand toward the top, and the other toward the bottom. You connect the lights to the app via Bluetooth first, but then switch to wifi. I found the app easy to use - and addicting to play with! The app enables you to control blink rate, led color and intensity, even lets you set up wave-like patterns which oscillate side to side or top to bottom (assuming you want that). You can also pick from a fairly bewildering assortment of pattern options, including recognizable flags and faces; to do that, you need to use your phone's camera in the app, so that it knows how you arranged the lights on the tree.For our tree, I picked a random color, slow-blinking option, which we customized for blink speed and light intensity - the slow blink setting with random color / random on-off lights results in a twinkling effect, something I was looking for.... And these are very bright - our current setup has the power level at 17%. Once you've settled on a custom lighting set-up, you can save it in the app - we saved two, one for me and one for my wife. After the lights were on the tree, the app setup and customizing our respective programs took less than 30 min. (and that included the argument about whose looked better)...I can't personally speak to reliability yet, but my stepson's have been working well for several years. These are indoor/outdoor lights, so I'm thinking of buying additional sets for some of my outdoor installations. In my opinion, these are well worth the money...
