Meh - it's winter in the Seattle area so I don't get a ton of sunshine, but these are inconsistent at best.  Sometimes they light up at night, sometimes they don't.  Sometimes they aren't lit up but if I jiggle them they turn on.  The bulbs don't spread out like in the picture - they're just clustered together.  Also, the little solar collector is attached at the base so you have to position them with that visible and not obscured by plants, etc.  I would have preferred to have them sticking out of bushes and stuff like that and they're not particularly attractive in the daytime ... but they're inexpensive so still worth it I guess.  I'll get a better idea once it's spring and we get more sunshine.
