Upright Elliptical Cross Trainer

Very happy with this elliptical - it's whisper quiet and takes up very little room. The stride length is perfect for me (5' 5") and my husband (5'9") and I don't have numb toes that sometimes happen on ellipticals when the petal is angled. We use it daily and have been very happy with the stability and quietness. When I assembled it I added extra white grease to the main pivot points, and plan to grease these again about every 3 months. I'd suggest keeping the tool kit handy for the first week to check the tightness of any nuts.
Yep, the tension arm was tricky - there is a nut that I point to in this diagram that may need to be threaded down further on the lower piece in order to be able to clip in the tension wire.
Update - now almost 6 months old and put on over 1800 miles - works great! I use it daily (50 min, about 11 miles) and it's so quiet and smooth.

Only had it a couple of days but so far I'm happy with it for the price.
It is very easy to assemble being 99% already done on arrival. I wanted something light and simple to increase my heart health, have bad knees so needed low impact.
Love walking outside but between northern Canadian winters and my dog being older and slower this gives a bit of a boost...10 mins burned 96 calories according to the monitor...I like that you can choose to go slow with small strides or faster and kick it up a bit, though it did wobble a bit when going faster, not enough to be concerned about it falling over and no doubt due to it's small footprint which I love having little room for exercise equipment. It feels fairly solid to me so I'm hoping it lasts a few years at least (some say the pedals break but I'm wondering if they are pushing the weight limit). If it breaks I will revisit this review however right now I am happy...

Ok I wanted to wait a few weeks before I gave an honest opinion. We’ll, I love love love this little machine! It’s nearly silent, easy to use but gets that heart rate up there. Finally an exercise I truly enjoy and do not dread. I can tell I’ve lost inches already! I can’t believe it’s down to $79 bucks now, I paid 89 for mine and was happy.
It was simple to put together, very compact and easy to move around. I’m only 4’11” so the stride is more than enough for me. The little timer / step counter works great, just push & hold to clear for your next session.

Excelente, trabaja muy bien, casi casi silencioso, para el armado ocupe un video de YouTube y super fácil.

I am very pleased with the Sunny Air Walker. It is very easy to complete the assembly and you're ready to go!
It folds up neatly to store too. It is very easy to use and you barely feel like you're exercising as it's so smooth running and virtually silent (no squeaks on my walker.) As you can use it indoors, you can watch the telly whilst exercising and the time flies. There's no real resistance, so it is a much more gentle exercise than say cross-training, but still gets you warmed up and your heart rate going. You feel the difference afterwards too, so even if you feel it's 'easy', it's still getting you active and the incentive to exercise is in it's simplicity and availability as it's easy to store indoors. I am very pleased with my purchase.
