The EXTERRA has a lot of positives to mention. As the name suggests, it can be folded, which makes storage easier. It is also very easy to set up. The treadmill itself works great. It runs smoothly, it doesn’t overheat when used for long periods of time, and it has a lot of options to let you build your own workout. There are a few negatives to mention. The biggest one is the fact that the incline options that the treadmill offers aren’t all that great. There are only 3 to choose from, and the max setting isn’t nearly enough for most athletic people. It is also very difficult to lubricate the treadmill. Overall, a good treadmill for the price, but with some issues that prevent it from being the absolute best treadmill on the market.
