will negotiate on prices,we bought this treadmill a few years back and of course like any other woman trying to get in shape starts buying and buying things that she never uses. we need to sell this treadmill to pay some bills. In total I've ran on it for about 3hours all together . the treadmill has a step incline which makes it like you are running uphill. inclines to 12 and speed goes to 10 miles an hour ,has a safety clip so that if you stumble or fall it turns the treadmill off immediately. has a fan built in. tracks your pulse and how many calories and carbs you burn. we have the manual and the treadmill is in perfect working order.
