I like how easy it is to use, as well as its efficiency with tracking my results in real time! There are some minor issues that can be improved upon (such as not being able to enter positive test dates/times). However they have been working hard at improving this system since we first started using them over 2 years ago. They were also very helpful when our IT department was having problems getting us set up properly so there wasn't any downtime once everything went live. We used their service before switching over from another provider who had gone out of business which left many clients without access to testing services after just one month into implementation. This has helped tremendously because now everyone knows what's going on with drug tests instead of depending solely off email notifications sent through other providers.
