iBoost Pro D8
Just back from 3 weeks in Spain and France. I cant praise this unit enough. The last site we stayed at in St Omer, the iPhones lost the site WiFi signal about 200m from the caravan. The booster picked it up in the caravan and not only that, boosted [my local WiFi] signal all the way back to the reception restaurant area, some 250 meters, and it was still showing 2/5 bars on the iPhones WiFi strength!
Excellent piece of equipment. No longer need to keep going to campsite receptions and sitting on the walls to pick up emails etc.
