When I was putting together the specs of the kit I wanted fitted into the motorhome we were having built for us in Italy, one of the key requirements was maintaining internet connectivity and preferably at the operating lowest cost as we are travelling for about 3 years all around Europe. I had Adam send over an IBoost and a roof top mounted 4G rooftop antennae with 12V charging connection. The antennae was fitted by our dealer with no problems and the mifi unit and charger sit on the wall inside the bathroom cabinet. We have not had to use the 4G setup too often as we are usually able to access wifi, but when we have, it works flawlessly and certainly amplifies and delivers the available signal perfectly The roof top aerial is slimline and unobtrusive. The IBoost system is an absolute winner and has given us good stable wifi in many many places where we would have struggled or had to use expensive local data SIM cards in the mifi. These are worth their weight in gold and certainly one of our best purchases. I bought the carry box as well and this was money well spent. Whilst not condoning such practices for a moment, for the cost of a coffee you can find out the wifi password at a nearby cafe then point your antennae back at them and voila - internet for as long as you sit there. Adam has given me lightning fast support on the couple of occasions I didn't read the instructions properly. I write this now sitting in a camper parking area in Istanbul where the wifi is far too weak and other campers have to sit outside the office to read emails on their phones. We are cosy and warm inside the camper while the Iboost does its job for us. Thanks Adam for a great product and overall great service.
