Query: Loved it until the battery died

This pedometer was great - easy to use, easy to wear and fairly accurate (good for walking, but poor for any type of jogging/running since you can only use one stride setting). However, the battery died after three months. I'm considering buying a few replacements for the rest of the year, but by the time I spend the money, I could probably buy a nicer version that will last longer. I would definitely recommend for someone looking to try out a pedometer for the first time - it's cheap, low-key and makes you want to start walking more. Just know that you'll have to replace it pretty quickly.
