I didn't have much of a chance to evaluate the device but from what little I did do I can say the thing WORKS both 3G and 4G. Its easy to configure via the browser interface too. I works both wireless and also via the USB connection. I did purchase an external antenna for it and that was a complete failure (no way to know if its the Mingle ant connections or the antenna itself.) I was hopeful the additional antenna would push a 3G location up to 4G but the signal strength basically didn't change with the antenna connected. All in all the Mingle is well worth $20...
Sometimes doesn't work with 2 computers on it.

I use this about once a month on occasions where I am just updating results for a live event and I have not had any issues with it. It is easy to use, took very little time to set up and I was able to change the SSID with very little issue. The reason I gave it 4 stars was because the documentation with it was a little bit wrong and I had to use a different ip address to access the settings for the device. Other than that, works with no issues

I bought this unit several months ago to use with iPad and Laptop when traveling and also as a backup to my home internet service.
