This video will give you an idea of what the comet will look like through different instruments (as well as how to find it). I was able to see it as a small fuzzy spot with my 10x42 binoculars. https://youtu.be/FYtfxeOQWiA

A 10x50 pair from the same website you posted will work better as you want as much aperture as possible and magnification is less important.
