Not sure if this was mentioned but Inmarsat now no longer allow pre paid units to roll over after the expiry date if you top up.

I contacted them last week to top up my unit and they did say they would allow 75% roll over without top up until October.

Thanks for doing all this research Rex!

After reading this series of articles I was going to go with renting the Briartek Cerberlink for my upcoming Sierra High Route in July see if you'd like to join us.

I thought I should Google the Briartek and look at some reviews first and found Rex's review here in BPL in which he writes "Bottom line: I will not rent the Briartek Cerberlink again. I had serious problems with both the device and the iPhone app."

Rex also wrote, "I really wanted the Cerberlink to work well". Me too. Thanks for giving it a spin and letting us know. I'm posting this here so it's connected to this series of articles.

I'm glad you found the articles and my experience useful (I would not call it a review).

I should point out that some reviewers were relatively happy with the Cerberlink:

Hi Rex,

I read your article back in April and picked out the Yellowbrick as looking the most interesting. I bought one and took it on a JMT thru-hike a few weeks ago. I was very pleased with it. I am putting together a review here...

Thanks again for the great write-up you did. Very good work.

Great review, thanks for spending the $$$ for the battery run down tests! The most outstanding feature of the Yellowbrick is incredible battery life.

Another Yellowbrick review, reviews are still rare:
"In my opinion the YB v3 is (arguably) the best two-way satellite messaging and tracking device on the market."

And another Yellowbrick short story about a North Pole trip, from an Australian dealer:
"At some times on the trip, even some of the satphones were frozen solid, but the Yellowbricks just never stopped working, getting positions and data out to the base team for the entire trip."
