This is a great dehydrator. I use it a lot and I like it a lot. It looks great. It’s easy to clean. The controls are easy and fast to operate. The temperatures are accurate. It’s very quiet. I highly recommend this dehydrator.It’s almost perfect. Whoever designed this didn’t R&D this and didn’t think it thru. The fan in the back of the unit does a great job of moving the air, but the air is blown unevenly over the trays because of the fan hub in the middle of the unit. In front of the hub there is little to no air movement so the food items on the center racks do not dehydrate evenly. On the center rack, the center third is still moist when the left and right thirds are finished dehydrating. The dehydration margins are gradient, so it is difficult to separate the dehydrated foods from the hydrated foods on the center rack. See my picture for an illustration of the fan hub in the back of the rack and a top view of the center rack and how the foods are unevenly dehydrated.There is a very simple and inexpensive fix to the design miss. Place a spiral louvre plate over the fan opening. That will swirl the air around the box instead of linear uneven air movement. I may make my own plate, but in the meantime I just use 8 racks instead of 11 and leave the center racks out. I’m happy with doing that to make it work but I shouldn’t have to when there is such an easy design fix.I still gave this five stars because I like it and continue to use it so much. If you need a good quiet dehydrator, buy it. You will be happy too.Update: The racks are about 1/4” off of square. It’s difficult to know how to orient the racks it load them. Hit and miss. Frustrating. Square racks would have been much smarter.
