Review (4/5): Works great but runs small
I bought this product to protect my 13-month-old's ears after she had tubes placed. At first she hated it and would rip it off, but my husband somehow convinced her to wear it, and it works great! Really keeps the water out and is very sturdy.
The only problem is that even on the largest sizing, it's a snug fit. Granted, my baby's head is in the 99th percentile, but I don't see how this would fit most toddlers.
