We were a little disappointed by the attention to detail, as we received "completed" phases of the project that had bugs or did not operate properly, however, this is to be expected. The bigger area for improvement is the timeline: our project took more than twice as many months as quoted to complete. However, we are very satisfied with the end product...We were just disappointed by the speed.
