Question: Noise Level Since I'm in an apartment building, I was wondering how loud this air-stepper is to use?
Document: bought this about 5 yrs ago off the TV for $100. best money i ever spent. i know some ppl have had issues with it being plastic and being loud. mine has lasted 5 years and i use it pretty regularly. i do it while watching tv a lot. sure its on the loud side making a swish swish noise but i don't mind. i love the stepper. i feel it in my butt and legs and i think its a nice cheap alternative to a more heavy duty stepper.
I like how it has air chambers instead of pistons.It's easy to use and store.As i exercise the time goes by quick and before youknow it I'm done exerciseing
I ordered what was on this picture, but instead received a different model: a twisting stepper that is NOT what is advertised here. I was expecting this air stepper, since I owned a previous one from a retail store. The actual air stepper works great, it is the seller that did not send the correct one! Do not utilize this seller!
I've been using the Air Stepper for about 3 weeks now. It arrived quickly and with no assembly required. It's light weight, easy to use and perfect for someone who needs low impact on the knees. I use it while watching TV. I haven't tried the DVD that came with it yet. I seem to get a good workout without it.
I purchased this stepper because it is an Air Stepper and so easy to use. I am 66 years old and like to exercise but many products are just too hard for me to use. This is one of the most excellent ways I have found to get exercise and still watch television ..:)  Totally portable, lightweight and extremely well made. I would encourage anyone who wants to use a stepper to get this one! !
It's so much fun, and the noise is very slight, just the pumping of the air, just turn up the tv and you won't notice. It was VERY challanging the first time, I olny logged on 15 minuted, but by the second day I was able to double that to 30. :) Tip: work your way up to using the resistance bands, or start out by using very light hand weights like you would for jogging. Its a blast! ENJOY!!! :)
This is a great product. I have used it for years. It is great for the glutes and easy on the knees. A great workout. Very portable form place to place in my home. I dont use the bands too much. The air mechanism is easy to work and very convenient. The timing device is a great addition. Hope you never stop making it.
Thanks to Air Stepper (and my grandma for the $100 gift) for helping me get my life back! I feel great!
I had this air stepper for only a couple of months before it broke. The air bladder busted and no longer holds air which makes it pretty well useless. I used it every evening while watching TV. At least 4-5 times a week for an hour or so. Worked great for awhile and then like I said after a couple of months ..... :(Gave it two stars because when it worked it was great! By the way I am 5'5&#34; 155lbs.
I bought this in January 2010 with $100 I got for a Christmas gift. I debated buying the WiiFit or this stepper, and am SO glad I bought the stepper. The first one I picked up at Big 5 sporting goods didn't hold air in the bellows, so I returned it and tried a new one, in hopes it was just a random defect. The second one has worked marvelously for over a year and a half. At the outset, I needed to lose about 80 lbs.
Answer: yes
