Review on Portable Treadmill Spinning Exercise Smartphone by Jon Conner

. It arrived broken and defective. and buy again. I decided to send it back and not buy it again. My phone kept falling off my bike! It had to be screwed really tight and when you ride the bike it will tip over and force you to stop riding the bike so you can fix it again. It's not worth the money for the stress it caused and my phone fell off the street. Keep this company in mind as they received the item through Amazon. I send it back with UPS and they never send a replacement or contact me for a refund. I tried to get a refund from Amazon. On a product I am returning that arrived broken. I don't recommend them to anyone
