I use it twice,three times a month. G to Richmond Hill via 401 and 407 and back and also 401 to 403 sometimes. Works well for me. Empty, fast, good surface.
If I had to commute on it tho' I'd be asking my employer to let me expense the trips as it ain't cheap.
Industrial strength Velcro works well for the transponders. A small packet from Home Depot is enough for many cars.
