Query: Unfortunate

I purchased this product after a decent amount of research - and evidently didn't do enough. I've owned manual treadmills before - a lot cheaper - and much better quality. THE BELT STICKS - THERE IS BARELY ANY FRICTION - which makes it very difficult to achieve any consistent exercise routine. DON'T BOTHER WASTING YOUR MONEY !!!
