Although I had high hopes for Yaegoo's resistance bands, my interactions with the business have been less than satisfying. The bands were of high quality, but I needed some clarification on how to use them effectively. I contacted customer support, but they responded slowly and ineffectively to my inquiry. When you buy a product from a business and then get no help from them, it's frustrating. Based on my negative experience with their customer service, I would not suggest Yaegoo to anyone.
