Awl --

I haven't, but for the life of me, all I see are *disadvantages* to this
gadget.

The first is, of course, cost.
This thing is triple the cost of a 7 1/4" circ saw, with blades that are 4-6
times the cost of std circ saw blades. Not to mention the lack of
availability.

Next, I can't see that it can do *anything* that a circ saw cannot do. In
fact, a lot less, and with a lot less accuracy.
The only ""advantage" is that the blade is teeny, so you have lower sfpm,
and can get away with cutting rebar, etc -- and I wonder for how long,
before the blade goes kaput.

It has no plate for straight cuts, no mitre, it is basically a 4 1/2"
grinder with a trim saw blade -- $19 from HF.
They never say what the blade size is, but it looks 4.5 - 5".

As always, the infomercial is highly misleading. You cannot do sink-type
cutouts without using a jig saw -- pure geometry of a circular blade.

True, it could reduce kickback, in case of a snag, or cutting unsupported
"in air", but I never had a problem with that either.

That "spark test" with gasoline was fraud.

Another infomercial hustle, afaict.

But if there are different experiences, do tell.
