It measures under a meter at 92cm which is likely to be a perfect size for most people's TV set up. It also comes with mounting brackets so you are able top wall mount under a TV that you all ready have hung.
The only controls is the touch sensitive bar on top which again looks good, these are not physical buttons and being a sensor will therefore not suffer from any mechanical breakdown.
There is a 'Nebula' red tag on the front which I dislike as it does stand out, I may try and remove it or colour it black.
Having the Firestick built in is great, no messing about with other devices, one power lead, one hdmi and your'e done. As well as the HDMI (ARC) input / output you have an optical input and USB port however this is for service only and cant be used for USB playback.
The LED light / indicator is not too bright or offensive but from my first tests this doesn't turn off at all so is always on but it didn't bother me. It default boots to Fire TV and the interface is identical to all my other Fire Devices.
Sound quality is great with a very good 2.1 channel output and the inbuilt sub is surprisingly good and offers a decent amount of bass. This is Dolby Audio but not Dolby Atmos. In my tests I did get a better sound quality with my Echo Studio connected to my Fire TV Cube as this did deliver Atmos however, this did end up costing around £120 more!
You can also use this as a stand alone bluetooth speaker and this is easy and straight forward to set up.
As far as I can tell you can't hook this up to another Amazon Speaker although there is rumours that this may change in a future update.
Overall I am very happy with this as when you look at the cost of a 4K fire TV device and a decent sound bar you are likely to spend more. I have this set up as the sound system in my 2nd lounge and it does a decent job. It doesn't and wont replace my 5.1 surround system though.
