It does what it says, could do with higher resistance for the legs and it does squeak, had to take it apart a little bit to spray some WD40 on it.
Other than that I am using it every day and would recommend it.
Easy to set up following the instructions. It's a must to watch the DVD before you start to avoid injury. Great page of exercises given that can be followed as a plan. Would suggest start with the lowest resistance and build up to prevent sore muscles.
Really well built piece of equipment,strong/sturdy construction has really boosted my daily exercise routine,compact stores easily,pricewise it is top value for this core exerciser, I have no hesitation RECOMMENDING this product !
