So easy a caveman can do it
Size: 32.8ft, Size: 32.8ft
Installation was easy and not complicated at all. The app lets you decide the mood you want the house in or wherever you choose to install it. I placed it under my island in the kitchen. It is perfection. No remote control. Very durable. Super bright. You can even turn it down a few notches but that's through the app with easy follow instructions.

Work just fine as long as you’re careful!
I don’t often write reviews, but I thought it could be helpful information since I’ve been through a few sets of these lights.
Pros:
- Good, easy to use app
- Bright, responsive lights
- Great customer service
- Low price, especially for the length
Cons:
- Fairly easy to tear/break
- Cannot use solderless connectors to navigate corners (to my understanding)
- Hit or miss functionality
- Not Alexa compatible (which is stated in description)
I’ve purchased three sets of these lights, ultimately they are good you just have to be careful.
1. The first one worked ok for a while, but they stopped working, presumably, after my cat bit part of it
2. I ordered another set since they had been working fine until my cat got to it. When I received this one, it was clearly not programmed correctly or there was some other technical issue with it as it would not respond to the app, though the app would say it was connected and would flash random colors in random different sections. I contacted customer service who walked me through some troubleshooting and ultimately sent me a new set, which arrived very quickly, which was greatly appreciated.
3. The third set arrived and seemed to function just fine. After installing them in the same way that I had installed the first set of lights, they soon ended up tearing at a turn point (I used their suggested technique for navigating corners) and no longer worked past that section. I tried to find any solderless connectors that I could use (now that I had at least two sets of partially working lights) however I could not find any that would be compatible (which makes sense given these are RBGIC lights and Govee themselves also stated this to be the case)
Ultimately, I don’t think I will buy another set and will probably just spend a little extra for a different set of light strips, likely from the same brand since a different model I’ve used before (TV backlights) has worked well and is Alexa compatible. Plus, Govee’s app is easy to use and has a nice UI.

High Quality Product, especially for the low price point
Size: 16.4ft
Very High Quality Strip Lights that can easily be adapted to any environment, fitting in even very small areas. The adhesive material on the back provides strong adhesion to most surfaces, with some common exceptions. They are more than stable in the vast majority of environments, and the remote control, either the provided one or the digital app works extremely easily to provide a good experience. The colors are vibrant and bright and can be controlled or dimmed easily.

Easy to put up and decent quality
Size: 16.4ft
These were actually pretty easy to install - and the cord to plug them in was really long, which is appreciated. I do wish they had more colors to pick from but it’s a great deal for the price.
