Review on Dionlink Unlocked 4G LTE Router with SIM Card Slot - Reliable Wireless WiFi Hotspot 4G CPE, Compatible with T-Mobile and AT&T (2 Antenna) by Alex Panda

Good point: Installation was insanely easy and the device worked as expected. I have 40 Mbps and 15 Mbps in an urban setting near San Jose, California. Directions in English and Chinese. As far as I can tell, verbose logging wasn't a problem. It looks like the device supports some kind of WAN fallback, but I haven't had a chance to test it yet. It would be nice to know from the manufacturer what to expect, whether there is load balancing between WAN and 4G, etc. Cons: No option to connect an external antenna. I don't understand why this device should cost so much. Appears to be an inefficient market. The device makes a cheap impression. It's strong enough to work with, but the weight should be measured in grams as it doesn't seem like much.
