These were a good price for the quantity. (I try and avoid using the pink one though as I don't think my boy suits pink yet)
They have been particularly useful when teaching baby to drink from a spout, as the plastic backing minimises the wet from spills and when allowing baby to feel the food being eaten, as the long sleeves protect the sleeves of baby's clothes.
They've lasted well considering the number of times they've been washed.
The only drawback I've had has been that the corners of the velcro fastening cut in to my baby's neck but this could be because they are a little short in the arms for my tall baby, as it doesn't seem as bad when I pull the sleeves up to his elbows.
Overall a useful purchase.
