Review: They sound good - They work really great and sound good
Review: Nice for audio alerts, plenty loud for one room. - I have them on a KOOBOOK mp3 playback module and an esp32 that’s monitoring a solar panel system and the volume is plenty loud enough to hear across the room even with the volume turned to the middle of the range. These mount from the front, that is the mounting ears are flush with the front of the enclosure. For my purposes it would be better to have them flush with the rear to allow surface mounting but I can use standoffs.

Size and look is great. Appear to be made decent and good value. Just too quiet for sound effects in a cosplay suit.
