Hab with two snowflakes decorated my window and let it burn about 2-3Stunden every day. There were already batteries inside, but held only two days. One sees weak batteries also equal because the star no longer as bright lights, but gets darker. After I had done purely new batteries, I had this change after about 2-3 weeks once and only once the sucker stick again (I have previously warmed him something, he has held great!). The fall (as the suction cup lacked) the star has also survived, the two plastic halves are out of joint but could be put back together again immediately. I really like the look, especially because several LEDs burn in Snowflake. All LEDs still function. The color is cool white, which I think fits very well for snowflakes.
