Review on Lifegoo Silicone Electronics Insulation Soldering by Nick Brunner

I ordered these because I solder a lot and work on a lot of small parts with small screws. I received the product last Monday and the valves in the three compartments that were supposed to close just kept opening after they closed. They send me a replacement which I received today and the same thing happens. Even the slightest movement of the mat or placing an object on the mat and they just pop up. I'm not sure what to do with it now. I bought it because it has compartments for clothes, not the ones that have open compartments. A little disappointed with this product.
