I have one of the generic ones (that I paid $15 bucks for) connected to a laptop power brick and it works well with 20 year old 3-way speakers.
To be fair, this includes a power supply which could account for another $15 and a case which would be about $10. So net $40. Hence $45 is a decent deal I suppose if you don't have an old brick lying around.
However, the most annoying thing about this is that it automatically powers down either the Bluetooth connection or the amp when there is no audio signal. Every time it powers on or off, there is a medium loud pop out of the speakers. Since I have this connected via Bluetooth to my laptop, then after 30 seconds of no sound, then there will be a pop when it powers down, and then the next time there is audio, like from a notification or if I start playing a video then there will be a pop and then about one second before it will start playing audio again. All of the pops start getting very annoying after a while. If you are playing continuous audio, like if you have Spotify playing in the background, then it will keep the audio signal alive and there won't be on and off pops all the time. But if you don't have a continuous Source playing, then the pops will drive you crazy. I don't know if this revised version has fixed this problem.
An optical digital input...this lets you hook the optical audio out of a TV or other device to play it. The old one had an optical out..which could connect to a DAC but is not very useful for most people.
2 Aux/Line inputs. This connects to a headphone out etc. It does not seem they are switchable, so they may be both live at the same time.
On the negative side, they removed the low level RCA preamp outputs, putting in instead a single subwoofer out for a powered active sub.
The power supply has twice the amps (4 vs 2) of the old one.

Mode seems to have a hissing sound. On Bluetooth it's flawless. Not sure is $45 is really deal considering a newer
Model is out from the same manufacture.

I tried it on wired and wireless, and it's very clean. The one I have, compared to the video, have a very hefty power brick instead of bulky-headed powerplug. I also added the left/right RCA on my subwoofer and it worked fine. The new version is also 100w x2 while the older one is 50w x2 so I am really tempted to get one (I got my old one for about ~60 USD).

So depending on usage model, the new version might be a downgrade or an upgrade. But from the wattage-alone spec (2x 50w vs 2x 100w), this new model is an improvement. For comparison, here's the link to my old one from Amazon [amazon.com].

I checked it again, and like what Groch said, the RCA ports were changed from Output to Input (and same for Optical), however, the new one gained a dedicated low-level subwoofer out. It will depend on your use-cases whether this is a pro or con. In my current old one, I can either use the Blutooth or the 3.5mm but not both (or maybe I was doing it wrong). I prefer using the 3.5 input jack and for audio, I prefer using wired connection in general so having a 3rd input will be nice.

the only issue is the 1Mii may lack power when you drive less efficient speakers (take KEF 350 for example). i ended up with SA 300 for my KEF but still kept the 1Mii for a more efficient 3 way speaker.
