Sounds neat, and the device itself is reasonably priced ($99 for the next 30 days). $14/GiB isn't a steal, though. There are better-priced data plans out there (T-Mobile has a 11GiB plan for $70, for instance).
Depends if you use exactly 11GiB a month, no more no less. Many people use a hotspot more one month, less another month. 11GiB for $70 is absolutely a great deal for some people, but not most people.
