Thank you for viewing. I got bored after only three days and haven't used it at all. I don't remember the retail price or the manufacturer, but I'm listing it at a low price since I'm getting rid of it. Additional note: I've raised the price slightly due to shipping costs. A mat to put on the floor was also included. - Type: Ab roller - Color: Black - Material: Plastic, rubber - Features: Non-slip handle - Usage: Abdominal muscle training
