From the article:
The transparent Flipper Zero is available in a limited edition of 7,500 units and costs the same as the regular model: $169.99 in the US. Unfortunately for the 400,000 or so people who already have a Flipper Zero, the transparent shell won’t be available separately — I did ask.
They're like a Swiss army knife. They do everything you could want, barely. I love mine, I use it to help build little electronics projects to test sensors and read frequencies for development. I'm not using it for its full potential. I also use it to control the lighting in the house and play a few games here and there. I also use it for a Pomodoro timer.
