Terribly Disappointed
I bought this item for my youngest grandson thinking it would be a goo learning experience for him. I thought it would be a genuine crystal radio like the ones I played with when I was a kid. You know, where you probed a crystal with a cats whisker til you found a nearby radio station you could listen to through headphones. No, nothing of the sort. Its a miniature radio kit replete with a printed circuit board and electronic components and a miniature speaker. Still, though, I thought this might be a good teaching tool. To my dismay the instructions were written in only kanji characters, undecipherable to an 8 year old kid, The kit turned out to be totally useless and wound up in the trash.

Gift for my husband
My husband built a crystal radio when he was a boy, so I wanted to get him another kit. He was pleased and is looking forward to putting it together. Unfortunately, all directions are in Chinese, although there is a diagram.

Not a crystal radio
A crystal radio does not use batteries, it is powered by the transmitted radio signal.you

FM/AM Radio, instructions Chinese.
Not a crystal radio, just an FM/AM radio, also in Chinese, I had Google Lens translate, I'll share the translated copy. Aslo, too expensive for a unassembled radio, you can find some at similar prices that are assembled and sometimes cheaper.
