Good service experience
The service is very well explained on the website and in the instructions I received with the router, and further questions are rapidly answered. Router is easy to use. Experienced a stable connection even in rural areas and on trains (except when passing through tunnels). An improvement of the battery life and/or the time it takes to fully charge the router would be nice. A faster connection is also always desirable, but is dependent on the network not the router, I guess.

Simple & Perfect.
Upon arrival in my hotel there was an envelope from Tre, which contained the Silver Buddy with loaders, cables and spare powerpack. Activating was a breeze, everything worked perfectly. Within a few minutes it was up and running. I used the router every day, the whole day long and it never failed, even at sea I had coverage. Speed varies according to network coverage off course. I did not have to use the spare powerpack, the internal battery was sufficient for day-long operation.
Thanks Tre, perfect product, simple to use!

Great!!
I was very happy with the speed of the Platinum Wifi Buddy. Worth the price of admission for sure. Will definitely recommend to others.
