Fast efficient, friendly and cost effective. We have been using AJWEX  for transporting patient samples since last 2 years , they have never let me down and have been consistently brilliant. As patient samples have to be transported under subzero temperatures, it demands extra care and quick delivery. AJWEX have been extremely prompt in helping us to transport such sensitive material. Their customer service is excellent always giving that extra touch and I would recommend them to anyone. Quickest, most efficient courier We have used.
