I so badly wanted to love these pans. I was looking to upgrade to a healthy non-stick option and loved both the beautiful design and functionality. The first few months they were amazing--but slowly over time, they have become completely non-stick. I've followed the directions meticulously (never used cooking spray, never put them in the dishwasher, cleaned them silicone sponges, bought the GreenPan sponge) and I'm so incredibly disappointed. Every single time I cook, everything sticks. I've reached out to GreenPan's customer support but they were unable to help me with this and suggested I do the same cleaning process I've done several times with no luck. Our last set of pans lasted 10 years--but these only made it 1. Wish I would have known this before I purchased.
