CyncDirect Connect Full Color 40-inch Light Strip Extension (1-Pack)

It does have extension in the name, but I've bought light strips with similar descriptions that CAME WITH PLUGS!!! Nowhere in the voluminous description do I see an explicit call-out that other units are required to operate this one. On its own, this is an unattractive paperweight.

We installed three light strips with plugs and 2 extensions in our kitchen. These were SO easy to install and use with our Google display/hub. Even us senior citizens could do it. :) My husband loves that these can do just about any color and they can be bright or dim. Could have been stickier. Had to use some tape. Really cool.

These lights are constantly getting out of sync. I have reset the lights and deleted all of the routines on numerous occasions. They work great for a while. Then they might start coming on at different time, they might come on at 1:00 in the morning, very annoying, for now accountable reason. It was quite an effort to get these installed above the cabinets and it is not an easy task to climb up and reset them. So I end up turning off all the routines and manually turning them on. The only thing they have going for them is there is a candle light setting that is as close as you will ever come to incandescent light using LED. That alone is keeping them in place.

this hooked up to the other one very easy, so simple.

There are great for under kitchen cabinet or china cabinet lighting. The IOS app allows for automation to run routines to turn then on and off, set up color, etc. App can be a little wonky at times but will eventually allow you to set them up as wanted.
