I have used just about every saw out there. From plain circular saws
through the K-12 and our carbide toothed chain saws.
The twin does as well or better for the tasks we use it for than the
others in a lighter and easier to handle package.

What I don't understand is this:

Even with a carbide blade, running a blade backwards into the work dulls
it quickly -- it rounds over the cutting edge. With that contraption,
one blade is ALWAYS cutting backwards. Just the friction heating alone
should kill blades quickly.

Then there are the matters of the 1/2" wide kerf and the fact that
each blade only gets half the torque from the little motor.

The only good thing I could say about it would be that it's safer to
pull back into the panel to cut backwards.
