Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I love this rower! Excellent build quality, fairly simple assembly (took me about 45 mins to an hour), pretty clear instructions in multiple languages. The workout computer and included Polar heart rate monitor are superb. The rower can be set to adjust the resistance to keep your heart rate within a specified zone. The rower can also be used as a cable machine that allows you to target specific muscles. The machine is whisper quiet and the rowing action is smooth. It's compact and easily stored upright (fits in our coat closet). In my opinion, this machine is a better value for home users than other rowers such as the Concept rowers because it can replace a cable machine station. I'm very satisfied and highly recommend it.
