Its an overall great hotspot device. It connects to the best connection between 3G, wimax, and LTE. Its a little bulky but only because of the high capacity battery that takes a long time to charge. When it is fully charged it gives you a good 8-10 hours of constant usage which is not bad at all compared to other hotspot devices. Again LTE is not yet available for most areas and who knows when it will be as they are slowly rolling out LTE so it may be another year or so before you even get LTE service in your area. Its a great device and gives you good speeds if all your doing is surfing the web and checking emails while you travel. Most people are not going to be streaming videos because that will eat up your data plan in a snap.

If your looking for LTE speed now, then you'll need to go to another carrier. But if your willing to accept 3G and wimax for now which is still fast speeds for most people, then this device is excellent.

Sprint currently gives you more data for your money so thats always a plus compared to other carriers!

Great reception, speed and relablitiy! My Trifi switchs between netorks without touching a button and has the best reception I have ever seen from mobile hotspot. Only complaint is the amount of time it takes to charge the 3200mah battery.

Mobile-hotspot makers in general need to test their devices more in areas with poor reception, and this is no exception. While it doesn't have a severe overheating (and resulting battery-bloating) problem like the Overdrive - also from Sierra Wireless - it is in several other regards significantly inferior to that device.

* The antenna isn't as good.

* When first booting up, if it tries and fails to get a cell connection, it often decides to reboot the wifi side

* It has an internal web server for the configuration pages. If it doesn't have a cell connection, the advanced-configuration pages won't load. And if it has a weak unstable connection, it reboots the webserver frequently. This makes changing the configuration difficult and installing a firmware update (once you manage to download it through a different internet connection) impossible.

It may be good if you have a reliable strong wifi signal. But if you actually use it as a MOBILE hotspot, can you rely on that?

Works pretty well. I like how it sits vertically and the screen can be easily read. Can be used on Sprint, RingPlus, Freedompop and possibly other 3rd party companies re-selling Sprint's service. Mine is currently activated on RingPlus.
