Luckily, I've had the opportunity to try many different Eliptical machines. Yes. There are some good machines and some bad machines. Some have "terrible" geometry in both ankle / feet and leg positioning and others seem good. And like with all machines, it has to be "fitted" to one's body. Even vehicle seats are adjustable for both up and move front back positioning - to properly fit each unique body. If one has short legs then a Eliptical machine made for longer legs actually causes more harm then good. And if too much ankle /feet tilt, it creates more harm then good as well. Majority of times, people get leg, ankle, feet or toe pain within a short usage time is because that specific machine "isn't properly adjusted (or fitted) for them". Just like peddle bikes, stationary bikes and other "machines", one size doesn't fit all. Its unfortunate that many Eliptical machines lack "user comfort" adjustments - just like many of today's vehicle and stationary bike machines.
