I had the ‘sun’ model of these - they’re cute but the plastic of the lens is brittle. The suction cups aren’t the best and if they should fail and let the light fall, you can pretty much kiss the lens goodbye. Within a week of arrival, all three suns were broken.
I found that the LED made to much of a single focus point and the lens doesn’t do much to diffuse the light, so they don’t really ‘glow’ per se. I put a single layer of masking tape over the lens, and that helped diffuse the light and gave a nice glow effect.
