Are Merach and Yosuda rowers any good?

Reviewer consensus is 'good for the price, not a Concept2 substitute.' Lifehacker and r/Rowing call the Merach Q1S a solid value with a durable feel, while r/homegym posts on the Merach R50 flag the monitor as the weak link ('the monitor is trash'). Yosuda gets similar treatment on Reddit — quiet and stable for beginners, but several users on r/homegym say they plan to upgrade to a Concept2 eventually.
