We're so glad you asked this question! During the development phase of our new aerobic step design we noticed that we were commonly finding scratches, scuffs, bubbles, small cracks and even slightly off-kilter interlocking pieces on our risers and platforms. After visiting the factory and speaking with our team of engineers, we discovered that these imperfections are a common part of the manufacturing process, are unavoidable, and do NOT affect the function of your equipment. Remember your aerobic step is meant to be stepped on! Knowing this, we love that each product has a rugged, raw, yet beautiful and unique appearance. Click here to see some of the common imperfections you may (or may not) see in your aerobic step equipment. (Any imperfections that fall outside the scope of these images are added to our Eco-Friendly Category of products and sold at a 40% discount.) That being said, if your equipment has been broken/crushed/damaged during shipment OR if any of the interlocking rubber attachments are loose or crushed, then please reach out to us so that we can have an opportunity to provide you with a legendary customer experience.
