I bought those on Amazon (for less) when Stu wrote about EMT snips on toolguyd.com.
Honestly, I don't see the craze. They're short and leverage is poor. I think they have their place but the cuts are terrible quality because of the serrated blade, so only for use when you REALLY don't care what the cut looks like. And I find them uncomfortable.
One thing that someone pointed out on Toolguyd (and he's dead right) is that they stamp that ribbing into them because they're so damn thin. It adds rigidity, but it has to because without it they'd bend sitting still. There's no heft to them, they feel like cheap China ****.
From the hype I thought EMT snips were gonna be super-mega-awesome but they're less than mediocre IMO. I caution the OP to not believe these are a panacea.

It may lead you to believe they're the greatest thing ever, just reserve judgment until you have a pair in your hands and use them.
