"I agree with your point, but like all generalizations, there is always an exception. You pointed all ONLY Maytag. Others exist. "
I never said ONLY Maytag had done it right with two easy handles to move the upper rack, only that from the searching I have done it seemed that way because I hadn't seen it anywhere else. And if you look at the price points most people are likely to buy, eg store prices of $600 or less, I think it still is likely true.
"As for having two per side, that is not really a bit problem because you just adjust one side at a time. Most times we adjust one side only and
leave the other where it is. No need to have four hands in any case. "
How is it possible to to only adjust one side and leave the upper rack lopsided? The models I've seen that have an adjustable upper rack also had 3 spray arms, as most of the better units do, with one of those being on the bottom of the upper rack. To move the upper rack, it has to be all the way up or down, so that the pipe connection for the arm connects into the appropriate one of two receptacles in the back of the dishwasher. Does your model only have two arms?
As for how big of a problem it is, that's something we'll have to disagree on. Having seen i done the right way, and valuing the abitlity to easily move the rack, I wouldn't even consider the models with the half assed 4 releases. It's just stupid, poor, design and IMO, inexcusable.
