QNAP NAS is a really good product, but I think the best part is the support for the products. Whenever I have a question or imagine something that won't happen, I can ask the support side. When the support engineer understands what I want to do, he does his best.
Customer support is effective once communication is established. A technical support person is required on both sides. The support is extremely knowledgeable and provides detailed support and explanation to any issues, as well as some will provide recommendations to the business needs as there are many different technologies or methods depending on what the business is trying to achieve.
