The LED candles see m. E. in reality even more beautiful than on the photo and product are probably designed more for long-range effect already because of their size (10, 13, 15 cm in height and 8cm diameter each). They can be used not only as a group but also individually. That the wax coat requires careful handling, is likely to be quite clear. The batteries could be used without any difficulty and without any damage to the coating. The remote control for several meters ('ve tried to ca 7m distance), a short distance even through the double glazing my glazed windows. After the preselected burning time switch with clearly audible noise reliably. To selectively burn "flickering" or even constant, makes this product particularly sympathetic. I currently do not have any statements, because the candles are only for a few days in operation about the durability. The manual contains a misinformation: Each of these requires 3 candles (not as stated 2) AAA batteries. The dimensions should be given absolutely in the product description, because for any purpose large candles are suitable.
Addendum: Unfortunately, the candles prove arge battery eaters. The smallest candle is not even two weeks in use, the two larger burned only on Christmas Day every 8 hours. The brand new batteries are all totally empty !! (Verified with battery tester). A few days later 3 x 3, so 9 !! Having to change batteries, is an evil imposition and an expensive business. Given this exorbitant battery wear, I will not buy this product with confidence and stage my opinion, based on two points down.
