Pros
Pro Advertised speeds are accurate in real-life use
Tep claims to provide a download speed of around 7.2 Mbps while in 3G areas, with 5.8 Mbps of upload speed. During Engadget's review, the specification speeds where achieved in real world usage. That said, speeds are very dependent on the particular country and geographic area you're in.
Pro Handy WiFi emissor
Tep Wireless uses Teppy, a very portable (4.2 x 2.3 x 0.5 inches) handheld WiFi emissor that has front display showing signal strength and battery life (maximum of 8 hours in use and 20 hours in standby mode). You can also use it to keep track of data consumption.
Cons
Con Some people have had customer support issues
A quick browse through international travel forums show that people have had occasional issues with customer support. This blog post covers one travelers particularly bad experience with the company earlier in 2013. It should be noted though that the majority of consumer reviews are positive.
