The only concern i've experienced was not with my direct service. We took the kids out and about one day and as we were pulling in to the Bashas parking lot on Ellsworth and Brown, a Units truck - loaded with Units pulled out in front of us (we had the right of way) and almost hit our van. It was concerning with the kids in the car...but my direct experience with Units has been nothing short of fantastic! Their Units are the nicest cleanest Units I've seen and i would recommend them to anyone who needs them.
