It is big. There is no temperature control and no on/off switch. It dehydrate quickly and the items are dehydrated consistently. I purchased the fruit roll up inserts when I first purchased this (older model). I have never needed to buy replacement trays or any replacement parts. I use this less now that my child is older. The first few years, I used it consistently on a weekly schedule and it has tapered down to once a month these days.Still one of the best purchases I ever made.Easy to use.If you dry something messy, the clean up is more challenging, but not horrendous. I'm one of those fairly impatient people. If it was super difficult to clean then I'd have stopped using it. BUT, I have maintained a 10 year relationship with it and have moved cross country twice and locally once in that time and it has been one thing that I haven't relinquished.I felt inclined to write this review 10 years later after trying a friend's newer, fancier, more compact model. It had nothing on my old workhorse other than more bells and whistles, being smaller AND taking 20 hours to dry raspberries. I'm sticking with my Presto. What some reviewers see as flaws, I find ease of use.And it honestly isn't that loud. I recommend not running it in front of your TV or next to your pillow. It is softer sounding than a blow dryer.I wish the layers were a bit thicker. Would love if they made thicker inserts for larger fruits so I don't smush them and break them.Bought it because it was fairly large and cheap. with some tweaking it works great for drying 3d printer filament.It has no temp control... or really any controls at all, but usually it seems to regulate itself at around 120 farenheit, tho it does wander from this significantly, It gets up to somewhere nearing 130 then the heater shuts off and it slowly cools back down to somewhere in the upper 110s before warming back up.When plugged in the machine turns on immediately and begins heating. the fan is always running and pulls air up thru the center of the machine and forcing it down around the hollow sides of the trays.I wouldn't say it's quiet but it's not annoyingly loud. it sounds a bit like a muffled hair dryer.I see this goes up and down in price but at $40 it's a good deal. No temp control, just always on if plugged in. It dried my peppers fast. This is a large dehydrator so it takes a lot of kitchen space but you'll have room for all your items. It's about as loud as my dish washer and it will heat your room up if you have the AC on. Probably a better idea to dehydrate your items in the Fall/Winter to save on house heating costs.I am happy with the product just plug in and use it, very easy.Easy to use since it is a plug and play setup. I have used several times making taco meat and regular hamburger gravel. About 6 hours and it’s perfect.We have only had ours a few months but my girlfriends sister bought one of these several years ago. Still going strong. In the last two year we have gone through 2 other brands that have trays that are flimsy and crack and break easily from the heat. The bottom of the trays on these are a lot thicker.Used it four times. Quit working for no apparent reason. Certainly not for being overworked. Avoid.I did not enjoy this dehydrator, although its my first one and im new to dehydrating, I found it odd there was no temperature setting or timer. Sort of flimsy, and also prefer stainless steal. Returned..Would recommend. Really saves time and mess. Good to dry fruits vegetables and meat for dog treatsI like easy to use products that are practical and work right out of the box - I just plugged it in, put my thinly cliced fruit in the dehydrator and checked on it periodically - yummy!Solide et chaleur dispersé uniforme. piment fort séchées en 8h très satisfait. Seul défaut est qu'il n'y a pas de réglage de températures. 70°c. Pour le prix c'est parfait. Les tiroirs sont solideA little noisy ......
