These shelves are sick! I do have gripes about them. For some reason, you select your color or scene, after a few hours they start doing a breathing scene and totally change colors. Then when you go to switch it back, its like the device loses communication with the app. Also not a fan of it needing to be connected to wifi. Would much rather bluetooth so thats an odd one. Edit* the seller did reach out and offered a full refund for the product without me getting in touch and without wanting the shelves back. Updating from 3 stars to 4 for outstanding customer service.
