I ordered the KitchenAid Pro 600 as an upgrade from my Tilt Head Artisan 325 HP 5 qt. Reason: Arthritis making it difficult to easily remove bowl. I just received my Pro 600 with lift bowl and have already made a chocolate cake and frosting. Remarkable ease of use and the bump up to the 575 HP motor was well worth it. I did NOT experience any of the issues that other reviewers have mentioned.....overheating, beaters not reaching all sides, unexpected stop of motor. I make lots of bread and heavy batter bakery goods and this unit is showing me that it will keep up with me. I do suggest all users really read the usage/directions and adjust their usage to get the most out of the KitchenAid mixers. Great investment and very happy consumer!
I would have given this product a 5, but the plastic lid/cover that comes with the product is cheap and doesn't want to stay on the bowl. You have to be very careful when using so it doesn't get caught in the attachments.Other than that, we are happy with this item.
