    I am overwhelmed with the quality of parts, the detailed instructions including photographs, the easy to read packaging, the simple assembly. And guess what? The radio works!
    My grandkids are so impressed. These kits are great for school science projects and Christmas gifts.
    Thanks for spending the time to make these available.
    I recommend the associated audio amplifer, makes the sound easier to hear.
