Do the Park master link pliers work reliably? Usually I can get a master link apart by hand, but then there are times when I have worn blisters on my fingers trying to get them apart. If the pliers work, to me they'd be worth buying to avoid the hassle. That, and I've got some paypal cash burning a hole in my e-pocket.
