This is cute, but the plastic keycap puller of the same design by Signature Plastics is much cheaper, no to mention that in this drop, the shipping of 8.95 to Canada is more expensive than the metal puller itself.
I've owned the plastic one and removed tight PBT DSA keys from my Clear switches without a hitch: http://keyshop.pimpmykeyboard.com/product/red-keycap-puller-wire
morintedIt is a matter of quality. Of course, for Canada, it is much more expensive than it is for me, but to US people, there is about a 3 dollar price difference. This is metal, that is plastic. The three extra dollars is worth it to some people and not to others. In your case, it is 9 dollars extra and it is not worth it.
