If we did not have Hindsite I would have to cut the service department in half. I could not see is being possible to manage and schedule without HS or a program equal to it.
Most of the problems with HS were on my end or my settings. Once I spent the time to learn how to really use it and trained the service techs HS is one thing we would be lost without.
The other thing I recommend is to use wireless devices that can sync all day. Samsung Tablets work great, but any laptop with Verizon "MiFi" solved some of the issues we had. Again, these were us screwing it up! LOL
