With a coupon under 20 bucks. This product fit true to size and its considerably not too tight just tight enough to provide you room to perform aerobics or exercise wearing it. I dont think there was an option for 10. I like that I can put a bike up against the wall in my garage and keep the rear wheel on the floor. You can do L & R TWS or dual speaker mode. Not exactly the same but similar. My dad was able to make this work on my truck. I would agree with all the ratings the controls on it are funky. Overall, I am pleased with the product. What a brilliant stylus!
