Review on 🌟 Prosperbiz RGB LED Spotlight: Battery Operated Accent Lights, Wireless Puck Light with Remote Control, Dimmable Uplight for Painting, Picture, Artwork, and Closet - Stick Anywhere! (2 Pack) by Jeffrey Connel

I bought these to recreate the old fashioned color wheel lighting on a miniature silver Christmas tree. From the start one bulb worked fine and the second only worked sometimes via the remote control, both bulbs worked as they should via the button. Revain's "tech support" didn't help (I had already done all the usual steps of changing and testing the batteries and testing cell phone camera remotes), so I was told to contact the manufacturer. 20 minutes wasted. Instead, I dug out my tools, opened up the case with a plastic spatula, and then found and repaired the cracked solder joint on the IR receiver pin. I tested the unit to make sure it worked, opened the case and now they both work great, my wife is happy (it's a miniature tree from her childhood) and Christmas is saved!
