What is it? It is a motion sensor that tracks your movement. This needs to be more than a quiet walk in the park. For me when I was on an elliptical machine, when I jogged, it was happy. When I was riding my bike (where my upper body doesn't move) it wasn't (unless I swung my arm). In no time I had reached my 60 minute goal, and I went to the website and entered the code that was displayed on the unit. There are no wires to connect, and no monthly fees. You just move, the Replay tracks your activity and you win rewards.
You can exercise 10 minutes today, 20 minutes tomorrow, and thirty minutes on the weekend. Its adds up your activity time automatically.
You can exchange the points for rewards (like gift cards from iTunes, Best Buy, Barnes & Nobel, Game Stop, along with Nintendo Wii, Playstation, and other items). For example to get a $10 iTunes card I would have to move for 22 hours. When you achieve your 60 minutes of activity, your unit will display your code until you clear it. With this in mind you could get the code, write it down, reset the unit, and have another code in 60 minutes.
The straps come in multiple colors and sizes and are made of soft silicone. Moving the unit from one strap to another is a breeze. I can think back to all the times I accidentally cut someone with my watch playing basketball, and with these straps that will not longer be an issue.
If you are a competitive person, their website has “leader boards” that display the people who have uploaded the most (ever), and the leaders broken down by the week, the month, and what state you live in.
While I originally thought the Replay was for young adults, I can see where a family could purchase the Replay for ever member of the family (they are $19.95) and make a friendly competition to see who has the most active hours.
If you're not worried about steps, or calories burned, and just want to have some fun staying active (and getting free rewards) the S2h Replay is the fitness tool for you. You can get them at amazon.com for $19.95
