Query: Stamina Elliptical Stride Review

Do not buy this product!!!!! I wish I could return it. The design is poor and you hit your knees on the handles as you exercise. You could injure yourself in a simple first attempt on this machine. Also, it does not have enough length and you have to stand with half your foot off the strider as you use the equipment, making the total experience more stressful on your legs and feet. I would not recommend this equipment for anyone.Don't be fooled like me. This is my worst internet purchase.And obviously my trust in Amazon is very diminished...I expected that Amazon personnel would have at least evaluated the products that are sold in some way before allowing it to be sold. This product should be removed from your website. Not worth the money.
