Having read some of the other reviews for this product, it is clear that many of the reviews are for the different versions of this item being sold by different traders. I ordered this item late on 19th Dec, deliberately choosing a UK seller with a good rating (Babz Media).
The package arrived before Christmas and properly packaged. I have had no reason yet to check through each one to ensure that they all work, but they are all in one piece. The few I have used so far have worked well and I have been unable to drain any of the included (CR2032) batteries, despite having them running for up to 8 hours a day over the Christmas period.
The only slight niggle I would have is that the plastic 'flame-shaped' piece on top pops off quite easily, exposing the bulb underneath. However, this easily pops back on with no issues, so I am being a bit fussy knocking off a star for that.
Overall, I would recommend this item but would also recommend not necessarily picking the seller with the cheapest price. Check the seller's location and feedback before buying (or buy direct from Amazon) to maximise your chances of satisfaction.
