Question: Is this Vapo Seal Waterless Cookware with 7 layers?
Document: Exceptional cooking set. I've had a waterless cookware set before but was delighted with some improvements that have been made since the last time I purchased. You will not be disappointed and the price is GREAT. The Price Pros wrapped it and delivered it quickly right to my door. Wonderfully pleasant shopping with them.
First off, this waterless set came nicely packaged in 2 layers of cardboard boxes. Quality is very apparent with the well-made lids, handles, stainless steel body. It's a truly beautiful set! The bottom is very thick (that's a good thing! ).Just a note: these are the ones without the steam valves/thermometer. They come with plain knobs, but for me, that was actually a plus. These will probably last longer than the fancy steam valves because there are no moving parts.
The way it's described on the amazon page, I actually think it's under-advertised! =)  I have not tried stacking it or using the poaching cups, but I'm excited to try!This one comes with a little booklet of simple recipes. I wish it had more as these recipes are harder to find online. But other than that, I think it's a great way to get into waterless cooking and I wouldn't be surprised if I were still using these a few decades later! =)
Great set of cookware. Heavy duty stainless steel. I would recommend this product to anyone looking for a great set of stainless steel cookware. Thank you so much.
The cookware is just beautiful! It is obviously made of quality material. It heats up so fast and cooks very evenly. One thing though. We gave it as a wedding gift, and it arrived three days later that the date it was supposed to be here. That is the only thing we were dissatisfied with.
Cookware performs very well at med-low temperatures. Food does not stick and cleans easily. Salt deposits inside, bottom of cookware cleans using a citric acid cleaner and the cookware recovers its initial shine. Outside the shine remains unaltered.
This is a great set of cookware. It's a bit heavy, but I have to tell you, it will probably last a lifetime. My first set is approximately 25 years old, and still looks really great. It's made from surgical steel, and it's very well made. I can't imagine not having a set of them. They wash up well...I prefer to hand wash mine, but they definitely can go into the dishwasher. The bottoms heat evenly.
Yes I like it very much it cook great I would buy them again I'm so glad to have the 17 PC
It's really not harder at all. In fact, chances are you are still in the kitchen when the lid starts to flutter (and therefore you can turn the heat down)...it only takes minutes before it steams...AND there's one less step. Here's why: I have a nice 16 quart steam-valve lidded stock pot from a different brand, and I have to close the steam valve in addition to turning the heat down.
I find that the food burn easy in this product. Expected more from pans and there not a way for refund for product
Answer: I can't remember how many layers.  It is great quality cookware...I even purchased a set to put into storage for my son when he marries or goes out on his own. Best cookware I've ever owned.  It is quite heavy though, but not as heavy as cast iron cookware. I have 2 sets I use and one in storage...then I also had another set my cousin kind of borowed and fell in love with them and never gave them back,..lol. I highly recommend.
