I usually trust in a product on Amazon with at least a 4 star rating with 100+ reviews. That model is 4.5 stars with over 2500 reviews. I think you are set!
all dehydrators are good........until they quit working and i don't think anyone has cornered the market on the best dehydrator - at least from the scores of reviews that i have read. my guess is, if you have good, clean power it should last a long time.
