You should only buy an Otteroo directly from Otteroo.com or from an authorized reseller. We strongly recommend that our customers do not purchase from eBay, Craig’s list, Facebook listings and other unauthorized sellers as we are not able to ensure the quality of the product and important reading materials and communications may be lost in the reselling of the product. Otteroo is made with the highest quality materials but as with all inflatable devices, there will be some normal wearing down of the product. Even if the Otteroo looks perfectly fine, we highly discourage purchasing a pre-loved Otteroo. Infants are more sensitive to discomfort and new experiences than adults and we would want your future swimming champion to have the best possible introduction to water!
