I have a 4g mifi with roof mounted aerial which has proven to be a great bit of kit. Yesterday it wasn’t working and on inspection the battery was dead, after checking it appeared that the fixed power supply to the mifi has packed up and so I emailed Motorhomewifi explaining the problem and as I couldn’t recall when I purchased the kit, asking if it was still under warranty. I received a prompt reply from Adam advising that I had bought it back in 2016 (doesn’t time fly!) but that if I let him have my address, he would put a replacement in the post!!
Brilliant customer service
