I am using QEX. Opinion - good but needs improvements they are supposedly working on. I came from my own stuff, not as sleek and sophiticated, so my expectations were higher than if I wasn't automted before and my dissatisfactions were harder to take. It is a slow program and cumbersome to navigate sometimes. Not real intuititve and a whole lot of learning and set up depending how you use it. I'm managing a few mowing/maintenance accounts and a few hundred fert programs and even more irrigation jobs. So to utilize the program in that many ways requires a lot of learning and set up. Fo awhile I thought I'd never get done becasue everytime I went to do something I'd have to go set up one more thing. I regard it as a late fall- winter project if you provide lots of services or evenings for a while if you are mowing/maint or application only. It is making life easier. QEX combined with my new Palm 515 I'm better organized with less forget or delay. I'm not using the palm with QEX yet but will do so as soon as I have more time. We still need the paper records in irrigation and applications to meet our own or government requirements.
