My review is more like a 4.5.Speakers sounds really good for the price. They were installed under a balcony at my parents with a recreation / pool house building.Bluetooth works GREAT and it was super easy to pair after the main speaker is plugged in.Cons: no way to turn off the speaker(s). There is no on/off so they are always on. Let’s say by the pool you wanted them off, well you have to unplug the main speaker. This means the blue light, seen thru the speaker grill, is always on. The speaker wire provided was not long enough (it’s a decent length for mostpeople) so I used car audio speaker wire that was better quality. Also, no mounting hardware included for brackets so plan on using your screws or Tapcoms based upon your install.Note: we previously had speakers installed in the same place so I was able to utilize the existing amounts that we had up…Overall, my gripes are minor. If they last 2-3 years I’ll be happy at this cost.
