    Alessio B. -Bologna, Italy

  • I'm happy to report that the trial on the QPV1 has been going well. I'm quite impressed by the performance of the unit. I'm also very impressed by the service that I received from Nick Archer which I think merits specific attention. Nick has been extremely responsive to my emails and questions. He has been patient, has kept his word, and has always replied to me quickly with an answer or a reply to my questions. Nick has provided me with what I, and certainly others in my group, consider to be a perfect example of top notch high quality customer service.
