I did have an issue when I first received my order (it was missing the pulp and juice cups and the reverse function didn’t work), but I was able to return and have it replaced immediately and my new one works great. I still have yet to hear back from the manufacturer about the advertised 4-year warranty and Amazon doesn’t give any information about it directly.
A tip I learned when feeding in your fruits and veggies: work with the slow masticating process of the auger by pulsing pressure with the pusher instead of just jamming the food in. This will keep your juicer in optimal function without overworking the motor or jamming it.
