I had an I-Drive (not sure if it was "Pro" model). It was a POS. Door worked ok for about a month, had to readust, etc, etc. Then starting not rolling up evenly (one side higher than other), door came off track, cables came off drums, bent door, and it hit me on the head as it came down (previously, I had had a belt drive unit for 7 years on the door with no issues other than the unit was noisy and the belt had stretched beyond adjustment). Had to get authorization from manufacturer to let Lowe's refund my money. By then, Lowes no longer had them and apparently they were "discontinued" - wonder if the "Pro" is a new and improved POS.
Now have 3 LM3800's - nice units, no issues.
