I'm pretty happy with these racks—brazed stainless steel construction is durable and should last a long time, and they're easy to clean either by hand or in the dishwasher.
The racks I received are bowed just a little upwards (the middle two feet on both my racks float just a 1/16" off the counter,) and, despite my best efforts, I've been unable to bend them perfectly flat. Nonetheless, this is a minor flaw and does not affect their use. In fact, with any weight, they sit flat wherever they are placed.
