My move with Smartbox was the worst experience with any company that I have had in my entire life. They simply did not show up to drop off my box. After telling me for two days that they were coming, they finally admitted they did not have a box for me. Eventually they promised I would be the first stop on the third day. They showed up at 2 PM, 6 hours before my flight to leave the state.
On the other end it took three calls to get an appointment setup. The first two resulted in them promising to call me back, but of course they never did. When the box finally did get delivered, they left two large metal straps around it so I could not even access the box. Currently I am waiting for them to make a new appointment to remove the straps.
DO NOT USE SMARTBOX.
