Bought the kb radio and Bluetooth 2.5" kit. Delivery was very quick. Product packaged nicely. Although pretty obvious and easy to assemble, instructions are clear. In the modern age of safety surprised to find the power supply connection to be a 2core (no earth) screw type block instead of push fit spring connector but it works. Speakers look OK. Sound quality (out of ceiling, not yet fully installed) is a little tinny and at high volume there is distortion. However full volume is pretty loud. I do have a battery bt speaker that has more bass... but I think it's acceptable for the price point. The app is frustrating, would be nice to be able to turn the speakers on/off without having to use the app, but I've not fully used it yet. However you can stream radio to the speakers and even youtube videos. Overall pretty happy considering the cost, quality and simple installation.
