It definitely exceeded my expectations. You can actually run on it! Although my main purpose for buying it was fast walking, I've now decided to combine brisk walking with short periods of light jogging. My sweet spot is 3.5 for fast walking and 4.5 for jogging.
I don't use it for a long time every single time (about 20mins), but at least I've started moving! The length of it is not too long, which makes it a great fit for using at home with my standing desk, so I can walk while looking at my computer.
Overall with this price, I'm very happy with this purchase.
