Expensive & doesn't always stick
Just hate how much these cost.  Our 3 year old has to wear them for a couple hours every day, so we go through them quickly and the cost racks up.  And for how much we pay, you'd expect them to work as advertised without issue, but that hasn't been the case.  We've had quite a few that simply don't want to stick to her skin/face.  Might end up trying an eye patch, but it's not easy with a 3 year old to keep that on her head/face.
