I wasn't sure how the build quality could be at the price point but it's very solid and well built. assembly was very simple and to the point. the rollers have a soft coating to them so it shouldn't do any damage to hardwood floors or anything from continuous use. the hand grips are soft and nice to hold and the elbow pads are soft enough to not hurt you during use. I found the included timer and clip unnecessary but it's nice to have at your finger tips but it doesn't look like it'll last very long. there are 3 adjustments to the handle to accommodate different leangth arms. I'm almost 6ft tall and mine aren't even at the biggest setting so it'll work for taller people too. the rebound in the rollers is just enough to assist with rolling back up but not too much where it subtracts from the feel of the workout. ot also included a knee pad which was nice and made out of yoga mat material.

Combining a rolling tape measure with a laser is genius. Makes measuring quick and precise.

I love the products and help my ab turn into better shape

Very good quality product
