I bought it in the hopes of causing mostly harmless mischief, but its capabilities in that realm are oversold.

That said, I knew very little about UART communication or SPI until I started playing with this and an ESP32 device. I also knew very little about bluetooth, RF, and RFID/NFR type stuff until I started exploring the world with this. It's been a fun journey that's rapidly advanced my understanding of quite a few things.

Others have said its overpriced or that you can build your own or whatever, but it's actually just the right price for a cool little educational tool that also works beyond the educational stage. It may even inspire me to build my own advanced version at some point.

If you're already a hardware hacker or EE, this is probably not much more than a toy for you. If you've always wanted to explore some of these topics but had no idea how to start, the Flipper is a good introduction. I immediately flashed it with custom firmware and it was easier than flashing my BIOS.
