I have not unwrapped mine yet to put up, but will give feedback when I do. I'm sorry that happened to you, @knittykitty, such a disappointment when you go to put up the decorations just to find out it's malfunctioning. Hopefully you can find something to replace it at one of your local stores, HomeGoods, Hobby Lobby, Michaels, etc.
I've had BL items that worked for a decade from years ago...I don't know if mfrg, and/or quality is different now, as this TSV wreath will be my first new item from them in 10 years...because they worked and lasted that long. (some went longer) I had two wreaths, used outdoors, in snow, all winter, as well as hanging window boxes with lit arrangements, lasted for years. I still use the baskets, after the lit greenery stopped working properly. Took out the inserts & plant real flowers in them in summer. Sometimes when you clean the connection or jiggle the wiring it will right itself. (But we shouldn't have to when it's brand new!)
Years ago I bought a Luminara TSV lantern from QVC that never worked right, the candle kept blinking not flickering. I love it and still have it because I'm always saying I'll replace the candle, which is doable, just haven't done it as yet. Contacted Luminara Customer Service & instead of replacing it (of course it was after QVC's 30 days) they thought it might be the battery case cover, that I need the "other type contacts" and they sent me one...it didn't even fit the lantern properly. I just gave up after that.
Just fyi on the topic of battery candles and Luminara...
I've started to buy (not that I need any, but got some tealights this year) my battery operated candles at HomeGoods, Marshalls...they have Luminara and other brands if you don't like Luminara, for half the price. My neighbor has had beautiful flickering pillars for a few years now, she's got excellent taste and gets everything at HomeGoods and TJ's. About $17.00 each (about 5-7" pillars of all types) vs. QVC's $70.00 for two!! (never would I pay that.)
