I had a Safe-T-Plus installed in April and I'm very satisfied with the unit. No additional steering effort is required as far as I can tell and while my rig never wandered a lot it is even easier to keep in lanes now. I haven't been in any super strong winds yet but it has helped when a couple of strong gusts hit crossing a bridge.
I can vouch for how much it does help when you drop a tire off the side of the road! I was on a narrow two lane Vermont highway when a big rig coming from the other direction took the corner too fast and cross the centerline. I swerved to the right and my right front tire dropped off the pavement to the dirt shoulder
; the drop was several inches and abrupt but the steering wheel never jerked in my hand and I was easily able to slow down and get back on the road.
Rig is a 2006 Camelot 40PAQ.
