Anyone tried troll motor "Mister Twister Shear Magic Weed Cutter"?

[Box]

Just wondering if anyone has tried the "Mister Twister Shear Magic Weed Cutter" on their electric troll motor? I just saw it on Cabelas, and think its a good idea, but would like to hear if it actually works before trying it.

Thanks,
