I chose this for many reasons below:1. Great review: 4.5 star with almost 1,500 reviews is pretty impressive2. Low wattage: 250 W, it will run 4 hours to cost 1Kwh = 37 cent3. Good price: the price is really good compared to most other dehydrator4. Clear racks so I can monitor the progress5. Round shape so there is no need to make sure the right directions to stack the trays6. Knob shows heating temperature7. PBA free productIt came yesterday, and it met all my expectations, plus:8. It runs quietly9. It's lightweight10. It looks niceMost importantly, it does the job. I want to dry vegetable, and in Cali's winter, sunshine is not dependable. This is a wonderful dehydrator! Glad I got it!!! When I have a chance to take a picture, I will upload it.
