Best praise vs top criticism for 3G Cardio Elite Runner
“Spirit XT685 is the best of the lot. I like Horizon 7.8 AT, but there has been a spurt in their customer complaints recently. 3G Cardio Elite Runner is slightly above your budget, But the treadmill is very robust, and the company has an excellent reputation for customer service. For that matter, you can buy their Pro Runner, as you need it for walking only. It is still the best of the lot in its category.”
“Landice has a 1 to 1 speed ratio. For every 1 mph increase in speed, it takes 1 second of time. This is about as fast as you will find. I think 3G Cardio Elite Runner comes in a close second place for acceleration. Some treadmills are HORRIBLE and can take almost 45 seconds to go from 2mph to 8mph. Crazy differences between treadmills.”
