I like that it's easy to use, there are many features for tracking your tests (both positive/negative as well).
The program does not have an option of uploading results directly from my phone or computer into their system - this would be helpful if you don't want someone else handling all aspects with regards to submitting test samples! There really isn;t anything i dislike about using them at present time though they do offer great customer service when needed too!! They provide excellent support in terms of being able to answer any questions regarding our needs within minutes via email etc so we can get back onto running business ASAP. We've been very happy since implementing these services but sometimes wish more people used drugspak instead than other companies out here who charge much higher rates then us. ! It makes managing staffs work easier by having everything centralized under one.
