I have had this several days. I thought this review might help someone in a similar situation as myself. I am in my 50’s probably 15 pounds overweight. Prior to COVID I did a couple of spin classes (people my age) twice a week after work and hit the elliptical at lunch 3 times a week or so. My only other exercise was climbing the steps to the 7th floor in the building where I work every morning. That’s would be about 180 steps or so. I’d be huffing by the time I got up there, heart beating...great way to start the day. I was looking for a piece of equipment to simulate this lost activity since I am working from home. I did get a cheapie elliptical to use at lunch. I had tried going up and down my own stairs but its not the same as 7 continuous flights up. I can say that this machine does NOT provide the same workout as climbing stairs in this manner. With the stepper set on its max height/tension I was able to do 300 steps without feeling as out of breath as I did going up the 7 flights. I realized why. Climbing real stairs you must lift yourself up step by step. With this piece of equipment you essentially are pushing you weight down on the steps. Believe me it’s easier! I can find myself shifting my weight to the ‘down’ side. I guess one should try not to do that! I have come to the conclusion there is no substitute for actual stairs.But that does not mean this is bad equipment? I have used it a few times. Not enough to decide if I keeping this (twist) model, returning for a regular (non twist) model or just returning all together.Equipment:The unit appears very well made and sturdy. It is not wobbly. It has very big foot pedals. While my feet do not feel like they may slip off a bit of a higher berm might have been nice. Unless the pistons die out, I would expect it to last some time. It says you can adjust the height. You can by twisting a knob and it does make a difference in two ways. Doing so does increase the step height. It also increasing the effort it takes to step. I am not sure if that is good or bad. I like the bigger step...recall I was trying to simulate a stair case. I can see where the tension on that size step could be too great for certain people though.Workout:Its recommended 15 minutes three times a week. I can see you getting a decent workout in 15 minutes. Just doing 300 steps in 3 minutes (?) I could feel it in my legs. It’s a different feeling that climbing regular steps but nevertheless it’s doing something! The thing is I was looking to replace a 3 minute activity I did each morning with something that got me a similar cardio workout. I do not think this is it. I am not saying its bad...just not what I was looking for.TWIST or NOT!What does twisting mean? I read reviews and spoke with someone at Sunny Health before my purchase. By the way, I got a fairly knowledgeable human on the phone within a minute! Regular stairs your feet point 90 degrees in front of you and up you go. This unit is not like that. Your leg sort of fan out as you go up and down. Look at the pic and notice distance between the rear steps and the front. It sort of feels like you got Chubby Checker on in the background and you are ‘twistin’ as you step. You do seem to get used to fast. My only concern is some reviews stated it started to hurt their knees. I have not used it enough to see if that happens. I do suspect you get a better work out ‘twisting’.Arm Bands.I have not tried them. Until I know I am keeping the unit I did not want to open them. I cannot see how the arm bands could be a detriment. In fact I suspect having them gives a you a little something to hold onto as you step. I suspect I’ll get used to stepping free handed, but for now the unit is alongside my elliptical and I hold the vertical bar with one hand as I step. If no harm come to my knees over the next couple of weeks, I’ll probably keep this unit and try the bands.Computer:Again, it I still boxed. It sits down by your feet. I doubly my eyes could see it! My experience with the things in this price range is not to expect much. However, if I keep the unit I will follow-up.Bottom line:It really wasn’t what I was looking for..but that may not exist. I don’t have spin class anymore. Perhaps this little guy can fill the void. I’ll do 300 steps each morning. And perhaps try two 15 minute sessions a week after work. I will try to follow-up in a month or so. It’s a sturdy piece of equipment that should be easy enough for anyone to use and has a small footprint. Just stream your ‘Lets Twist again’ and you are ready to go!
