Blow

Blow is a name that is used for more than one kind of product, so the safest reading is that it is a consumer item whose exact form is unclear from the label alone. By our assessment, that makes it hard to praise for a specific feature beyond the fact that the name is short and memorable. The downside is equally plain: without a clearer description, there is no solid way to judge what it does, how it is used, or where it sits against alternatives. In practice that means the item carries very little information in its name, which is a problem if someone is trying to separate a tool, a cosmetic or something else entirely. Blow is therefore too thinly identified here to earn more than a cautious, middling mark.
