ThinkComputers.org reviewed the Mountain DisplayPad and MacroPad
A quote from the article:
Smaller keyboards have become extremely popular over the past few years. I personally use a 65% keyboard most of the time. With the limited amount of keys available on those keyboards getting something like a dedicated number pad can not only be useful for gaming, but also work. On top of that streamers can really make use of products like this to easily switch scenes, cameras, etc. This is where Mountain comes in with their DisplayPad and MacroPad. Both of these keypads feature 12 fully programmable keys that you can set to pretty much anything you want. The DisplayPad features customizable LCD displays for the keys, while the MacroPad has typical mechanical key switches and keycaps.Mountain DisplayPad and MacroPad Review
