This device is so inaccurate! It will count steps, thousands of them, when driving, also will count steps when sitting doing nothing and also when sleeping (I don't sleepwalk). The worst part is, you could get over these inaccuracies if they simply had a way to pause the step counting...but they don't, you can't even switch this device off! That's right, cannot even switch it off. I tried to like it, I really did, because it looks good and it is easy to use the functions, but with this level of inaccuracy it is just not fit for purpose.
