Among my favorite razors, the Click I purchased at the Gold Souk in Dubai for pennies.

Mine, all black, is dubbed the "Cool Click," for its blister pack came with a Lord Cool DE blade.

It's the lightest razor I've ever used, which isn't a problem for me, and perfectly balanced at that.

EDIT: I don't know what the weight rating means. I judged on how much I enjoy its weight, not on how heavy I find it relative to other razors. If I went by that criteria it'd unquestionably be a 0.
