Product review (4 stars): Almost identical to original - a bit hard to snap together.
They work great and are nearly the same as my original ones, just new and nicer! They were a bit hard to snap together, so I used a hammer to gently & firmly tap the piece into the wheel which worked! First, I even tried putting the small piece on the rack before installing the wheel and that didn't work. Picture shows the original wheel on the left and this new wheel on the right (when I bought my house, there were 2 wheels missing from the lower dishwasher rack). Mine came packaged as 4 wheels together in one bag. Now the lower rack rolls in and out smoothly!
