"Great Single Board Computer Accessory!

This Duplex Hotspot is an excellent accessory for any Single Board Computer. As my tests showed, it's easy to set up and use right away. The device allows for simultaneous use of multiple WiFi networks, making it a versatile tool to have. The added heatsink keeps the device cool, preventing any potential overheating. The only downside is that the setup process can be a bit confusing for beginners. Overall, a great investment for SBC enthusiasts!

Pros
  • Easy to set up and use.
Cons
  • Requires technical knowledge to troubleshoot problems.

Excellent MMDVM WEAK ANTENNA CONNECTIONS WARNING

Great product except for one thing, the antenna connection point is very weak. I wish it had direct SMA connections instead of a small laptop WiFi antenna connection (I don't know the name), the SMA conversion would be significantly more durable

Pros
  • Computers and accessories
Cons
  • Functionality

Stopped working after less than a month of use

As another reviewer mentioned, the antenna connectors are quite difficult to attach, but using a flat edge I was able to break both. Unfortunately, after less than a month of use, my MMDVM hotspot stopped responding to commands via pi-star and now I have a $70 paperweight. Edited 8/4/2021: The seller contacted me. to make it right The new access point is a thing of the past. I've updated my original review but still emphasize the need to use a flat object to connect the U.FL to SMA antennaโ€ฆ
