After three weeks I'm still amazed at this equipment. Very smooth, good cushion, decent controls, and very solid feel.
It is a very large box and the pieces are very heavy. Two people recommended for the assembly. Videos detailing the assembly were easy to follow. This is my fourth treadmill assembly and it was the easiest by far.
Using the treadmill by way of the iFit software is straight forward and great for a runner/hiker looking for interesting/unique workouts. Using the treadmill in "manual" mode for more advanced training is still more difficult than it should be. So far I have yet to find a way to 'pre-program' a workout into commands that are just executed. But even having to make speed/incline adjustments manually I have done some of the most intense indoor workouts of my life.
I am happy with my purchase from Northern Fitness.
