I actually own the regular series of this product and I love it. I previously owned the type of dehydrator with a hole in the middle of the trays. It's so much easier to use these type, especially when I'm drying grains. It does a great job and heats quite evenly. I've been very pleased. The only thing I don't care for is the way the door attaches. It just hangs from a lip on the front. If you don't get it seated just right, it rattles. In fact, sometimes it rattles even when you do.
