I honestly was trying to refund this but there was no refund option. After receiving it , it was a lot better than I had anticipated. I liked it the moment I used it. it does feel similarly to a hula hoop and saves much more space as well. I thought it was going to feel cheaply made from videos I had seen on YouTube but it wasn't. it is much more sturdier for being plastic. The shipping time is fairly accurate and you may even get it sooner. instructions were a little unclear. But essentially, all of the pieces snap together and can be pulled apart individually. The final piece where the black attachment is found also snaps together if you slide into the inner slots correctly. You should ear a snap for every connection and the end piece. Tips: wear this around your Hips and not your waist, you will have more control over this. works pretty great, sorta reminds me of a weighted hula hoop. it's just a little noisy! but other than that, it's great :)
