true enough on most counts, but i found wind ups excellent for night time feeds/changes with my babies, as they give a nice low light so as not to distract the baby -who with a brighter light may think it is play time!!!- but bright enough for mum/dad to see.i found that if i gave it a good wind before i go to sleep, there is ample power to see through night feeds and the fact the light dims over time, this was excellent to settle my babies back to sleep.Unfortunaley they rarely live up to the hype, wind up are best kept as something in the boot of the car for emergencies.
