Concept2 is basically the gold standard when it comes to rowing machines, and their store reflects that focused expertise. Rather than trying to sell everything, they do a few things extremely well. The Model D rower and BikeErg are staples in CrossFit boxes and competitive training facilities worldwide, which says a lot about their durability. Free shipping is included and delivery in 3-10 days is quite reasonable. The purchasing experience is straightforward and no-nonsense, much like their products. My only real criticisms are the limited payment options (just credit and debit cards) and the 30-day return window, which could be more generous for equipment at this price point. There is also no financing option, which might be a barrier for some buyers. But the machines themselves are virtually bulletproof and hold their resale value incredibly well. If rowing or air-resistance training is your thing, Concept2 is simply the best in the business.
