I had following scenario in mind: amplification with minimal setup and no overhead for my family. This way I can practice when the children are asleep without being worried to wake them or my neighbors up. It's plug and play with the least effort: no power cable, no heavy lifting. Very important if you are in a lazy mood. Sub-scenario is being in the same room as your children an filter their noise out by the use of a headphone.
After some research the amplugs came up and it perfectly fits my needs.
I like Vox amps in general and they translated their overall speaker amp knowledge very will into this little tool.
The sound, volume and built-in effects together with the aux input makes it an excellent on-the-go or 'silent' practice sidekick. Don't expect the sound cloud of a full-grown combo or stack, that's not within its scope or goals. It's big in being little: portable, excellent practice tool. A better sound on this scale is second to none. Another pro that it is 180 degrees adjustable. I find that very important: if it is in your way somehow you can get it adjusted very easy.
I have yet to find any con in light of the situations I used it in. I misplace it often, but it is meant to be little. So that's not a valid point
