Review on Soldering Silicone Magnetic Resistant Insulation by Derek Wagner

Need a mat with notches like this for small screws in electronics to keep them in place and thanks to the rim nothing can roll off the table Workspace. The only thing I don't like is the closed compartments. The lids don't stay closed at all unless you cut them off the base, which I did very carefully with an X-acto blade that goes through the silicone like butter, just slowly cut to a clean edge to obtain. This is a very small detail though and we didn't need closed boxes anyway so it doesn't detract from the value of the piece at all. Great product for what we need.
