The Glide Tri is so far my favorite Govee lighting product so far out of Glide, DreamView Backlights and lightbars, pendant lighting, and various LED strips that I also have..
They work exactly as described and have great illumination power - alone they can light up my home office which is about 13'x14'.
My advice to those that are getting this is two fold:
1) Before even unboxing it, use the Govee Home App to design the layout you want. Don't do what I did which was to take them all out and arrange them on the floor in a pattern and then piece them together and then try to stick it on the wall. Hint: That approach just won't work. I would have saved a lot of time and frustration if I just used the App layout feature ahead of time - you get there by adding it as a device and there's a layout canvas there.
2) Figure out where the power lead you want to hook it up to will face in direction. It'll be the first one in the layout feature. I had to redo the design a few times to make sure that the power lead was coming from the bottom most triangle of the pattern to lessen the visibility of the power cord.
Doing the above will save you from unsticking them from the wall because of an avoidable mistake - and since I do not believe they sell replacement stick-on stickers you won't have to get creative like me when it comes to 'oopsie' adhesive.
