Review on 🔊 MiOYOOW DIY Spectrum Bluetooth Speaker Kit - USB Mini Home Stereo Sound Amplifier DIY Soldering Project for School and Home Education (Soldering DIY Kits for Learning) by Linda Nelson

I wanted to brush up on my soldering skills and bought this set. The Revain listing has a link with detailed assembly instructions. A lot of the soldering involved installing LEDs to show the musical spectrum. It took about an hour and a half to solder and assemble the plastic case. After completing the kit, I was able to instantly connect to the bluetooth on my phone and enjoy the music and spectrum display. The sound quality is comparable to other Bluetooth speakers of this size. I haven't tried the TF/SD card player function in this kit.
