I was sent the Ozeri 4x3razor Digital Pocket 3D Pedometer to review, and while I really should be using it, my almost 9 year old son has been wanting a pedometer for months. We actually think he may end up being a long distance runner one day, but for now, he likes to walk the mall with his 80 year old grandparents when he isn't in school.
The 3D Tri-Axis Bosch Sensor from Germany is certainly more advanced than anything that he needs, but it provides superior accuracy. It is actually designed for high-performance athletes, the 4x3razor is the world's thinnest and lightest pedometer -- 0.5cm (less than 0.2") thick and weighs just half an ounce.
It records steps, distance, calories, fat burned and exercise time with the most advanced Tri-Axis technology. It counts up to 1 million steps with 7-Day Memory, and includes a built-in Clock and Sports Timer with Auto Sleep technology.
Obviously this is way more than a 9 year old needs, but he loves it. He is already looking forward to Spring when he can start running. I may even start, as I should!
This pedometer is the creme of the creme of pedometers. If you are an avid exerciser, or if you know someone who is, this is for you!
