Pros: Flexible. Looks like a remote. Comes with the clip-leash attachment as advertized. Bumpy textures helps with the gums, while the silicone material is soft on the teeth. Baby likes it.
Cons: It's smells so bad when brand new, I had to wash it in the laundry machine with extra detergent for it to smell safe enough to use. The holes in the back are a hassle to clean, the design would've been better as a solid back.
I only knocked this review down a star because of the initial smell and the weird back design. Otherwise, I highly recommend this for your teething infant.
