This unit has good value as a portable unit. The fact that it can be wall-mounted anywhere gives it a big advantage over other echo’s. I have echo dot and echo plus. The sound quality on both units are great. The echo flex has a very small underpowered speaker. It’s ok for most voice responses but not for music. If you get a nightlight attachment This unit is great for a long dark hallway. Or a child’s bedroom. You can also hardwire or Bluetooth a speaker for a better sound but if you're going to add on more equipment just to do that I would recommend the echo dot. Overall it’s a good device but remember that it has a limited sound quality.
