@lupyuen Wow thats super expensive for what it is, it looks like its literally just the lilygo t-beam in a case which you can get for $30 https://www.lilygo.cc/products/t-beam-v1-1-esp32-lora-module. If you are actually looking for a mestastic device for on the go or emergencies i would instead recommend the lilygo t-echo assuming you can find stock anywhere because they are that good from what ive seen

@lupyuen looking at the rest of their designs its all the same, they are just creating enclosures for off the shelf lora/meshtastic devices. The cases themselves are also taken from some of the meshtastic community members with no acknowledgment according to the meshtastic discord server so seems like the only real service specfive is providing is printing out cases and sourcing parts and putting it together for a hefty premium.

@lupyuen while not yet officially responded to, the likely situation is apparent by reading to the bottom of this page:

In short, it _may_ be a matter of parallel code movements/copying from _within_ each codebase.
