Thanks Teri, I may check into an exchange. I do like it but it would be nice if my feet were inside the boundary. At just under 215 lbs I'm under the stated weight limit of 265 and it seems to work OK. I just need to get used to it. I've done one or two 15 minute sesssion the past 3 days and after about 8 minutes I worry a little about my eyeballs shaking around 🙃 I have used the tension straps to help balance but may start using my walking sticks. I tried a few slight squats while standing on it but not sure I want to chance it as my balance is not so great.
