Query: Good quality, easy to use!

This foot roller is sturdy, light-weight and well made. It comes with two extra spiky rollers that are easy to switch out and the non-slip lining on the bottom is a great touch. As a dancer, I'm on my feet all day and I've tried a lot of different rollers. Personally, I think a lacrosse or tennis ball is more effective (hence four stars instead of five), but this roller still feels good. Bonus: it works well on your calves too!
