You can see in the picture what comes in the box: Power Adapter, 2 reels of LED Light Strips, the Remote Control and the multi-function power distributor/IR remote Control receiver/Music sensor. I've also included photos of the various shades that you can select using the remote control. As you see in the picture, the remote control has lots of functions for selecting a single color at a time or selecting a variety of modes for cycling through colors or having colors change by music. I've uploaded a short movie showing one of the light cycle selections. Although the instructions say you can cut the strips, it also says you need connectors not included to connect up any strips you cut. I'm going to research that, but the instructions, unfortunately, didn't include info on what you need or how you'd go about cutting and connecting multiple strips as I'll need to do. If I get that info, I'll post it with an update to this review as well as pictures to the final installation once it warms up enough to be sure the strips adhere properly (& I don't freeze my tail off). In the interim, if you just search Amazon for "LED Lighting Strip Connectors," you'll find abundant offers and many come with instructions onhow to use. These strips are, I'm pretty sure, 10mm wide ones.
Comment on company's customer service - it's VERY responsive. The multipurpose controller in the original shipment seemed to have a problem. I reached out to the vendor and they guided me to simple tests to confirm it was the controller & not something else that was faulty and then shipped me a new controller. Took a few days to arrive, but it came in and worked right out of the box very reliably. I was very happy.
All in all, if you're looking to put up some LED lighting strips, this is a very cost effective route.
