It absolutely is! However, you're going to need to buy a small electronics "shelf" or other type of mounting system in order to have a Milo unit mounted to one of your walls. Here are two easy-to-install shelves that Milo is compatible with:
The first recommended option attaches to an existing outlet, creating a shelf above the chosen outlet and providing easy access to power. The second uses 3M command strips to easily stick up on the wall, allowing it to be placed anywhere you'd like. Both are designed with access holes that the Milo's power cable can take advantage of.
If you're looking for a different mounting option, just keep in mind during your search that Milo's dimensional specs are 3.4 x 4.1 x 7.4 inches (this is the same for the Milo base units and the Milo point units).
