Product review (5 stars): turned out a wheel was off making the rack close a little crooked and that didn't allow a good seal/alignment to the top rotatin
I've had mine for 3 years. The wheels are the only problem that i have had. I will be looking to replace 3. They've come off several times and now it is time to replace them. Just treat the dishwasher  well - I admit i can be ruff/get in a hurry to load and go.  Remember to rinse out the filter in the bottom periodically.  Once the top rack glass's weren't rinsing well... turned out a wheel was off making the rack close a little crooked and that didn't allow a good seal/alignment to the top rotating arm.  I put the roller wheel back on -no more problems.  Except i need to find replacement wheels.
I have a small house with a small spot for a dishwasher and this fits perfectly.
