Large magnesium tin snips, useful?

[breakfasteatre]

Noticed local homedepot clearing out made in USA husky snips.

picked up a pair for 15, looked like these:

curious before i unpack them how good they will perform? I need to do the flashing on some windows i installed.

any thoughts?

I recently came across a large old Malco set of similar style. They are straight and I thought they were shingle cutters or some other exceedingly boring thing.....But, they are tinsnips and work very well. I've always used Wiss and found the Malco style to be very handy for all sorts of stuff. Replaceable blades too.
