Funny, I bought one from deal extreme that looked exactly like it but with less nice finish.... got around to using it for the first time last month setting up my 727 and it didn't stand a chance against the KMC mushroomed pin chain... the prongs on the main body that hold the chain in place bent on the first try and the pin budged barely any... my park tool one ended up making easy work of it with barely any effort from me, plus no hex wrench digging into my hands.
I assume I got a knockoff of what you're talking about as I believe it must perform well enough for you to post it up here.
