I first bought this product two years ago. The toast it made over those 2 years was fine - not exceptional, just fine. One piece of toast would come out darker on the same setting as another but it was still toast. Then one side of the toaster (which controls two slots) just stopped working. Kitchen Aid replaced it without quibbling but then within 2 days the same happened to that toaster, and the next, and the next.
I am currently on my fourth replacement which has also just broken. The exact same fault has occurred with each. I am now awaiting a refund.KitchenAid Artisan 5KTT890BPM 4 Slice Toaster Grey
