I opted for the reconditioned unit when buying the AutoEgg and I must say I am so happy with the product. It works like brand new and gives that deep, fuss-free self-clean that ChillX has become known for amongst feline lovers. The reconditioned unit saved me quite a bit of money and was definitely worth it overall. One negative points was that the box it arrived in was used but that really didn't bother me as the product inside looked brand new. great design with no noticeable scratches or big signs of wear and tear. Overall, really happy. Cat loves it too which is always a plus.
