I've been using these pans for several weeks now and I've so far had no issue with them. Food seems to cook evenly and the pans heat up in an average time.
I would recommend these for anyone who is looking for a non-stick everyday cookware.
The only downside to this product are the rivets for the handles are on the inside of the pan. When cooking scrambled eggs, food will collect around the rivets. Not ideal for sanitary reasons if the pan isn't cleaned throughly. However it makes the construction sturdier.
