I have tried several brands and so far (after more than 6 months of daily use) I can say that I am very happy with this one.
It’s true that they get stained but be careful, they get stained from normal use, cleaning them is quite easy and the best thing is that no matter what food we cook, they are really easy to clean.
Of course, 2 of my pieces have started to scratch even though I use cilicon utensils, which seems strange to me, the scratches are superficial but I am very surprised that it happened, apart from that detail I think they are excellent, despite the weight and the material, they don’t take “AS LONG” to heat up as other brands of similar products, although if it is true that you have to let them heat up well otherwise the food will stick, so it’s the only tip that seems really necessary to me to avoid discomfort, without a doubt they are comfortable, easy to use and clean though Maybe for many people they are a bit heavy, but in terms of quality they are really good investment, if I had tried this brand I would have bought it 5 or 6 years ago without problem.
