“I have the 5qt bowl lift model and I love it. The only downside is that it doesn't do well with very small batches of meringue; but meringue powder is pretty inexpensive so I just make a little more than I need.”— districtly on Reddit
“No regrets.”— @derrickcarpenter5705 on YouTube
“Once I started baking bread I bought a bowl lift professional 5 plus. It is way tougher and works well, but heavy dough really taxes it and I have smelled burnt wiring a few times while kneading. I like the tilt head for medium duty work, but I don't think I would recommend a bowl lift to anyone.”— Thinkbeforeyouspeakk on Reddit
“As an owner of this model, I appreciate this video, because it ahowed me that, with just some basic knowledge of how things work and the effort to use that knowledge, this can be repaired, without engaging an "expert repair professional".”— @worshipgeek on YouTube
“This was an estate sale with the house up for sale as well. I don't think they knew what they had or its value.”— @monie1527 on YouTube
“I had a Kitchenaid Professional 600. I like to bake bread. I found while making dough that the bowl would flex a bit and move a little while the machine worked with dough. One day, I stripped the gears in that machine, and when I took the cover off to see what I could do, I noticed that part of the transmission housing in the kitchenaid was made of plastic.”— FanHassock on Reddit
