Not very high quality coating

only used a few times and rubber is already peeling off. Guess it is to be expected, but my API chains are over 5 years old and not the first creack or break in the coating on them.

Most of the pieces in this set have been great for most baking that I've done. The non-stick coating is very easily scratched, so you have to be conscious of the kind of utensil you're using before you take a cookie off the sheet. Granted, the non-stick works well and baked goods tend to just fall right off. Another problem I've had is that the seam of the cups on the muffin pan rust when put in the dishwasher. It can be cleaned off, but it doesn't seem to reflect the expected Calphalon quality you should expect. The pans themselves are very heavy, and I feel like it would be difficult to make them warp.

Also, I would like to make an addition now that a few months have passed from my above review. I used one of the pans to serve out of and the process of cutting bar cookies from the pan destroyed the non-stick finish and it has rusted in the places where the finished came off. I find this to be troubling for a pan from such a well-respected company.

I bought this about a year ago at a target for cooking.  My roommates and I all got very good use out of it, about twice a week, for about a year.  Fairly quickly the non-stick coating began to fade and just recently it began rusting.  For $25, I wasn't expecting much so I'm not surprised, but for a long-term investment, look elsewhere.

Lighter weight than expected, and lacking in nice, smooth finishes. There are hole punches in the handle that are not smooth to the touch.  The pan has a slightly elevated/raised cooking surface that makes it look warped. Mine came dented (not from shipment) and the nonstick was chipped off the corner.

Nice, but easily Scratched and Ceramic coating is quite thin.  good price, but still disappointed

The primary reason I purchased this product was the enviro non-stick coating. So far the non-stick coating is holding up better than some other non-stick cookware I have used, but I can't say that the non-stickiness is any better. It is a decent pan, but a little expensive. It is hard to be more than 3 stars excited about a pan, but overall it is a good purchase.

I've had these for a few weeks now and they are nice and heavy, but we forgot one time and used a metal spoon and it scratched the finish already.  The finish on the back/outside of the pan is already deteriorating as well, and we only handwash them.  It is nonstick, but the instructions say to follow recipe directions and use nonstick spray or shortening or whatever if that's what the recipe says to do.  I am not sure why because nothing seems to stick, but using the nonstick spray is starting to stain the pan already, and of course you can't use anything abrasive to get the stains off.  Also, they certainly let the bottoms of some rolls burn, and some cookies got quite over done as well, so they sure don't stop that. I'm glad they were on sale and I bought them to replace the cheap crap I've always bought that is black and warped, so hopefully they will last.

Nothing special or particularly amazing about this. Expected more from the manufacturer but oh well. The interior should have a smooth surface, but it is textured and causes more sticking than is acceptable to me. I rarely use it and went back to basic iron skillet.
Soak it for a while and the stuck material cleans off well, but that's about all I can say. Oh, the blue color looks good for whatever that's worth.

Worked just fine with no color casting; however, it attracted dust too easy.  With this price, I expected more on its quality.  The glass reflected too much and also not easy to clean.  It should work better with nano coating on both sides, it does not.

These pecans were not as good as I expected.  The quantity was pretty small for the price and I didn't care for the glaze.  I would not recommend them based on the above issues.

For the price, the product lasted for 6 months and the coating has started to come off. This isn't what I expected. I use it specifically for breakfast cooking so no heavy stuff there and have been taking the utmost care with no scratches or anything, the spots on the surface that give it the stone appearance seem to be what has started to roughen up and protruding out. Not that happy with the purchase.

I pulled the pan out of the dishwasher the other day and noticed a chunk of the coating was gone where it was resting in the rack. It took the coating off of the rack too. I will have to contact the company for a replacement. CHEAP...

The pan arrived quickly, looks nice and is lightweight.  Fit great on my burners.  I heated it over medium heat, grilled a thick piece of salmon for about 15 - 20 minutes (it was a big fillet), and we ate it, all fine.

Then when I was cleaning the pan I saw these white spots on it.  The black nonstick coating just came off on the first use and I was looking at the white/silver metal underneath.  The pan never even had high heat on it.  The black coating must have been on the fish and I guess we ate it.  Now we'll probably get non-stick-coating-cancer.

My husband says that's what I get for buying this cheap pan, but I've cooked on lots of cheap pans that don't come apart, for years.

Next time I'm sticking with heavy cast iron, will season it myself. So disappointing.

First of all, I understand that I can only expect so much from a product priced this low. Nevertheless, I did hope that this pan would work well for a much longer period of time that it ended up working. I liked its size, it fits a single egg perfectly. The construction is OK, nothing extremely solid but it feels sturdy enough.
The biggest upset had to do with the nonstick coating. I followed the care instructions religiously, but after just about a week of daily use I noticed that the pan has started to loose its nonstick properties in a couple of small spots, so every time I attempt to cook something with it, even after applying some cooking oil, it will stick to these problematic areas.
All in all, I am not satisfied with the product but I can't say I lost too much because I didn't exactly expect it to be that great based on the price.

For 30 years I had used and loved my set of stainless steel copper bottom pans.  We replaced our stove with a glass cooktop and unfortunately my beloved pans danced when boiling water or simmering sauces and things took way longer than before to heat.  Rather than risk breaking the cooktop I decided to purchase new pans.  Two items of importance to me fast even cooking and dishwasher safe.  After some research I found GreenPan Rio.  Safe coating and supposedly dishwasher safe and significantly cheaper than stainless pans that were of comparable quality to the pans I was replacing. I was very disappointed to find that although the cooking was even and fast after two runs through the dishwasher the silver band at the top has rusted and a couple uses after that I have found that the ceramic coating is pitting.  In addition, after I simmered tomato sauce in it for several hours I found that the white coating now had a slight pink tinge.  I'm giving up on these pans and going with the more expensive stainless.

I bought 3 different sizes of this pan and was all excited. What can be better then a ceramic coating? And for a couple of month I was very pleased with the results. But the performance deteriorated slowly, and right now 2 of them are in the trash and I just ordered a new pan and upon arrival, the third will end up in the bin too. I cook every day and got good use out of them. But at some point you have something constantly sticking to them. It looks like it "burned" into the surface, and I'm actually pretty good with "not" burning my food. I have one of those ceramic pots and you can always clean it completly, but I suppose the ceramic coating of this pan is not optimal. I guess you get what you pay for. The good thing is that they are not that expensive, they look nice and as I said, the performance was great when they were new. That's the reason I give 2 stars.

After a few uses, the metal coating started peeling. Lucky I noticed the tiny metal bits in my pressed garlic.
