Review on 🎄 Holiday Joy Christmas Bubble Switch: Illuminate Your Festive Season! by Lauren Russell

Bought five as gifts. Three were ok and worked well. However, two have reverse connector polarity, rendering them unusable. (The bubble light points down, not up!) I'll attribute it to cheaper Chinese goods for now. BUT be careful if the buyer tries to use the new Revain system and refuses to print a label. MANY small UPS centers are not equipped for this and so I lost the return window. It's not the manufacturer's fault, it's Revain who should have posted the warning.
