I use a pair of Bose S1's for my smaller gigs, similar to the altos but not as much power, and a bit bigger. I bought the Atros to link to the Bose using a cable with the Bose on stands and the Altos on the floor pointed up for bigger gigs. That was the plan, but I now use the altos for gigs instead of the Bose. Nothing wrong with the Bose, but the Alto has more sound and effects. What I like- well almost everything. Small, not too heavy and runs a long time. For a case I bought a long playing record case that was made to hold 80 L.P.s and put some padding inside it. A cheap way of making a case.
What I don't like- well only one thing really, The volume control is designed to be used from an app on your phone. I don't use a smart phone so I have to hold a button down on the amp to adjust the volume. Not a deal breaker, but it would have been nice not to have to do this.
I liked the amp so much I bought a second one. (and made a second case like the first!)
