I purchased this First Year Massage Action Teether for my infant. It's age 6 months +. He really enjoys it. It's easy to hold for him. It's durable and battery seems to be long lasting. However, it should note that you cannot replace batteries. I also find that he really has to chew hard for the vibrating function to work. I believe I paid $8.99 for mine at Shoppers Drug Mart.
