I have too but I am the party pooper here to give it negative feedback.
If you live in a mountainous place forget it. Going up the mountain OD is useless and you cant stay in second the whole way and 3rd gear (1 to 1) will bog out especially when you get behind some dork in a prius who cant keep up. so you end up going from 2 to third constantly and every time you downshift....there goes your mileage.
Coming off the mountain, OD is useless and you cant stay in 3rd the whole way to keep your speed in check so you end up in a constant shift battle again between 2 and 3.
Same situation with a one to one ......keep in one gear down from normal and ride it the whole way through.......wont bog and wont rev you up to much because they are closer ratio wise anyways.
All depends on where you live and what you are going to with it. As a commuter for me, it didn't work because living in Colorado, gives new meaning to the long and winding road through a mountain pass.
