Review on Perixx PERIPAD-303B Full Size Backlit Mechanical Numeric Keypad with Office Shortcut Keys - USB - 22 Keys - Kailh Brown Switch Keys by Unm Weil

The description says these are Kailh Brown switches but they are actually low profile Kailh Choc Brown switches, good or bad is, depending on what you are looking for. Be that as it may, this is a thin, compact, low-profile mechanical keyboard that performs as you'd expect. All numeric and arithmetic functions work on a Mac, but no digit lock (which never works on a Mac) or dedicated copy/paste/cut keys. Keyboards are advertised as only compatible with Windows, so this is no surprise. It would be nice if it could be programmed so that you could use it as a macro notepad. But to be honest, you don't expect that for the price. So if you're looking for a thin, inexpensive, low-profile mechanical number pad, this is a solid choice.
