The 2 lamps don't flicker like a flame & one quit working altogether after 1 day. I already own 2 so I know how they work. Seller said they sent 2 replacements & provided a tracking number, but it's been 11 days & Uniuni has no record of the number. Seller has not provided a return shipping label & has asked me to determine the best way to ship the bad lamps to China. I'm not paying anything more until I receive 2 working lamps. I can't find an "Ask eBay to step in and help" tab, so not happy!
