I'm annoyed by this online vendor and I'm venting here. Take it as a warning or whatever.
I purchased a new type of exercise loop (R-Loop), one used for rehab. I ordered 2 different strengths and they were pricey! However once they arrived, I found that they did not follow the traditional resistance levels. My "light" and "medium" had practically no resistance at all.
I tried to contact the company for a RMA (the website said it accepts returns on new items for 30 days). After 3 attempts, I finally made contact and was told that once I'd TOUCHED the product, they couldn't accept a return.
So basically...they don't accept returns. Which is not what their website said. So...that was a $36 mistake. Buyer beware.
