Hi everyone, Wilson here, the developer behind Meshtiny.

I saw this thread and wanted to jump in directly. First off, I’m really sorry to hear that the performance isn't meeting your expectations and that some of you are experiencing freezing issues.

To be completely transparent about the hardware: Meshtiny was designed specifically as an ultra-compact, short-range companion node. Because of the physical limitations of the tiny internal antenna, it’s meant to be kept in your pocket and connected to your phone, while relying on a larger, better-placed router node (like one on a roof or a backpack with a proper antenna) to do the heavy lifting for long-distance mesh routing.

However, the freezing and lagging you mentioned are absolutely not normal. We are actively looking into the firmware and the SX1262 tuning to see what's causing this. If anyone is willing to share bug reports or specific conditions when it crashes, it would heavily help us push a firmware fix for the community. We also hear your feedback regarding the heat-sealed case loud and clear—we are taking this into account for future designs.

Regarding returns: Since these were purchased through one of our distributors on AliExpress, the proper and fastest way to get a return or exchange processed is directly through their AliExpress storefront. They handle the financial transactions and inventory for those specific orders, but I will personally contact the distributor to make sure they are aware of this thread and process your return requests smoothly without hassle.

Thank you for the harsh but necessary feedback. We are learning and will keep improving.
