I picked this up while it was on sale so I could spruce up my whiteboard a little. The water levels seemed quite low in comparison to the image on the site & it was hard to see the example images through all the glitter due to the water only going about halfway up each magnet. When I took the back off the first one, the picture was already damp & wrinkled due to the tiny rubber stopper being loose on the plastic casing. Turns out this was the case for all 3 magnets, with the stopper just falling apart (and in one case getting lost in the liquid when I attempted to take it off so I could reseal it). I think this may have been due to humidity or something & not necessarily a production error (as if it were just an error I wouldn't expect all 3 to be leaking).

I'm sure they can be fixed by refilling them then using a waterproof sealant to stop them from leaking but I haven't gotten around to doing this yet. They're cute though & aside from this big problem, I'm still quite fond of them. Not sure they're worth the full price though as the stoppers are very flimsy so they seem quite cheap.
