I might add that a few of these products are sold in stores like Walmart, Walgreens, etc., locally, at a lower price, much lower.
I purchased one product at Walgreens after seeing it on tv, an alternate for shaving your legs, plucks the hair with a rotating coiled disk. Still have it and I'm still using it.
But I remember Teflon pans, never lasted more than a year. I have cast iron for some pans and and use stainless steel pots/pans for most of my cooking. I have a saute/omelet pan that use for most things, just 2 of us to cook for.
I do check online for reviews and cautions, sites that have no agenda. Reviews by unsatisfied customers.
