We don't have those, but we do have a couple that are supposed to glow in the dark. But it's the old school glow, so you have to hold them up to a light for a while first. And it doesn't last all night. So basically it was useless. We just make sure we use brightly coloured ones in the crib and save the clear/light ones for elsewhere.
We have the Avent ones and you have to hold them up to the light. They only glow so long. Doesn't bother me though, I put her to bed with a handful of binkies so she can feel for them at night.
