Since I was tired, tedious distribute lights on Christmas tree, I tried it with this wireless candles. Two were unfortunately defective from the onset. The external appearance is quite nice, the lights do not like it quite as good, with my lights it seemed warmer. By batery candles are quite heavy so you need to make sure that they are fixed only at strong branches. My conclusion: You save work, but I will probably not use every year, but give me every now and then the trouble with fairy lights.
