The purchasing experience was first rate, excellent product description and easy to use website. No problems with delivery the product arrived fully boxed, undamaged and on time. The product worked out of the box and was all I had hoped for. The problem is post sales service and product quality; the product stopped working after 4 weeks. Repeated attempts to make contact and agree a satisfactory resolution have been ignored. Have been trying since September 2018, and haven’t received any acknowledgment from Nex G Mobility. Unfortunately for this reason a one star rating is unavoidable.
