Have three others but this one has temp control and power button on unit.Really noisy but gets hot enough to dry turkey jerky. Love it.PleasedFirst, I dried a bunch of hot Habanero peppers. This machine is fantastic. Buy one. You will be impressed! I do have one problem with the directions for using too much cure with ground beef Jerky. I am experienced making Jerky with sliced meat, but ground beef was new to me.I made some ground beef Jerky last night. I see a problem with directions for the 2 sample packs of Jerky cure that come with the machine. In the directions for the Presto Dehydrators 2 sample Jerky cure packs, It is suggested to mix one pack with one pound of ground beef. (One pack includes Cure & Spices, separated until using). Most cures are like that. I don't know why. Maybe they react if pre-mixed.I had a little over two pounds of real nice freshly ground beef, so I put in both packs as directed. It turned out way too salty, but edible. Note: I mixed the packets very well, sprinkled it evenly on the meat, then I hand mixed the meat for a long time. Then I laid down strips with a "Jerky Gun". Using that is an art in itself! I suggest holding the Jerky gun at about 45 degrees and keep the nozzle touching the shelf while pulling the gun along as you go. You will learn very fast. Note: Jerky Gun is not included. They are sold separately.I bought the Open Country Jumbo Jerky Gun w/3 Tips: Wasn't to sure about this item, but once I got and used it, oh my! Have made our own garlic powder from your garlic bed, no more wasting the cloves. Am about to try drying potatoes, excited by the many prospects. Others said it was to noisy, but I really didn't notice it that much. I'm really happy with my selection.This is my first dehydrator so please keep this in mind when reading my review.Pros- you can make jerky with this and it is digital controlled temperature-making healthy dog treats is a snap-great for dehydrating herbs like cilantro...the stuff that you buy in the store that goes bad soon and you throw out 90% of-amazing for prepping for camping or long term storage-comes with 2 fruit roll up trays-comes with 2 inserts for foods that can fall through the regular tray-comes with 2 sets of spice for jerky and a great instruction manual-breaks down to half the size for storage-easy to useCon- This is where my inexperience comes in. I am not sure if all the dehydrators make the same amount of fan noise. Was expecting some but did not think it would be like that. Ended up setting it up down stairs as I am a bit sensitive to this kind of noise.In general i am quite satisfied with spending a few more $$ and getting a good unit with digital temp control. The standard ones with one temperature limit you a lot.Update feb 2020I use this in bursts. I like it quite a bit. Very useful for camping. It gets stolen on me...alot... by my mom and neighbors wife.Tras unos meses de uso tengo que decir que el deshidratador se ha convertido en un electrodomésticoindispensable en nuestro hogar, hemos deshidratado frutas, verduras y hasta chiles, todo queda siempreexcelente y la factura de la electricidad no ha aumentado apenas . A todos nos encanta y disfrutamos muchode los resultados. Además es fácil de limpiar.Great product. Have been using it consistently for last 15 days since I got it. Only problem, it runs on 110 Volts and required an additional expenditure of a Step Down Transformer for IndiaIf it wasn’t SO NOISY it would be perfect, but it does the job of dehydrating and that’s why I bought it.While the machine is good quality and easy to use, the drying times suggested are not accurate. I followed the instructions for preparing the fruit, it took about 6 hours more to dry them correctly.
