The user interface makes it easy enought at first use so that newbies can get their business going like I did without having any issue in understanding how things work when needed later if they do encounter such problems. So far we haven't come across anything really bad as our experiences have been very pleasant thusfar while using this system here's why : 1.) Reliable2.). User friendly3). Easy installation4)."Saves time"5."No downtime". The product is very easy to use, and the customer support is very responsive. It is also easy to integrate with our other applications. I have not found anything I dislike so far. The only thing I dislike is that the product is a bit expensive. It is a great product. I highly recommend using it. We are solving our problem of locating our employees in the warehouse. This was a huge problem for us.
