Great customer service. Ordered the 18 inch by mistake and discovered they do not yet make a 36 inch roller. To my surprise Mobiltas told me to keep the 18 inch and also emailed me various exercises to use with it. How considerate and kind. When I received the roller, it was as described and made of sturdy, dense material, not too hard for me, but I have used rollers in the past. Very well made. Will definitely want to order from this company again.
