I purchased this teether for my 4 month old daughter who has started putting everything in her mouth. She absolutely loves it, and favours it over other teethers when presented with a selection. She especially loves biting on the ring as opposed to the finger-like knobs, but either way you look at it, the soft silicone helps relieve her sore gums. My only concern is that it's a magnet for lint and hair, so I am constantly washing/rinsing it, luckily it's easy to do so. I would definitely recommend this teether!
