Works the the way it’s supposed to otherwise and has some other nice features like a max temp alarm and a countdown timer as a couple of examples.As the title says, I have used this in the past to make chocolate toffee crunch. The toffee comes out perfectly. Now, unlike other people who have reviewed here, I have not used another candy thermometer so I have nothing to compare this to. Also, I have only used it for this one recipe, which if you ever tried would agree that it was worth the price of the thermometer!Regarding the thermometer, the clips to keep it attached to my cuisinart 2 qt work fine. The thermometer seems accurate. As they say, the proof is in the pudding so I can't tell if the temperature is accurate, just that when I take the toffee off the burner at the temperature indicated on the thermometer (and in the recipe), it comes out perfectly.One side note though...My advice is to not count on the alarm giving you fair warning that the temperature is approaching. Perhaps I have not been able to figure out how to use the alarm properly, but I set it for 280 degrees F to give me a little warning before it hit 290 degrees and it didn't go off until after it had already reached 290 and I had it off the burner. Luckily I was watching.Therefore, make sure you WATCH the temperature and (another tip) make sure you watch it very closely as it closely approaches the temp that you need as it goes pretty fast then.Hope this helps.Purchased this on 6/10/15. Its worked fine until today. Probe malfunction, but now past return date. New probe is $17 and change....New device is $20. I won't be ordering devices from this manufacturer again.Update....I am happy to upgrade the rating to 4 stars.....It would be 5 but there is the issue with the probes. I have, thanks to very good customer service, (Rikki), had two of these units encounter the exact same failure about 40 days into use, it is the probe...not the device. The device is quite good for the money and CS is exemplary I am sticking with it on the DCCT-S. Its alarm setting for over and under temp is good within 2 degrees. Once you know that, its a breeze. I make cheese so to use a simple thermo is more to watch with a lot going on.Bottom line...Great device but get an extra probe so when and if the orig fails you have a backup while you wait for warranty replacement.I had this model for years and would still be using it if I hadn't dropped it in the water filled sink. Registers quickly and accurately. I've used it to check oven temperature. I would like to keep this as long as possible.At first when I set up the product I could not get the probe to go into the holder. My husband figured out you have to pinch the holder to allow the probe to go in. I emailed the company about this as their directions did not indicate this. They never responded.Overall, once you get used to the machinations it could work well, but you have to make sure the oil is touching the probe correctly, otherwise you don't get a good reading....I would give it four **** compared to other products I have used through the years....I love the features on this thermometer! The timer and temperature alert combination is incredible for cooking because both values are so important. The temp alert allows you cook it internally to perfection but sometimes you want to check it after 20 minutes to make sure it's not over-browning. Great features.First annoyance is that the buttons are hard to press - you have to hit them just right. Not a deal break but annoying. The biggest problem was that a couple weeks after I bought it, the bottom left portion of the LCD broke making the thermometer unreadable. They are replacing the unit but at my own shipping expense. Maybe this one is just a lemon...I'm pretty happy with this thermometer, which I primarily use to make yogurt. I like the digital read out & the ease of reading that. Yogurt making requirers good temperature control.The magnets could be a little stronger; & the probe attachment to a pot of hot milk could be designed a little better. Cleaning the probe also could be made easier.Bottem line, the yogurt is coming out great, as good as I can buy in a store.works wellI haven't used it many times yet but am pleased with all the functions and I can watch the food temperature without opening the oven door. The numbers are a good size and the unit itself is magnetic. As I have a double oven, I can attach it to the oven door at eye level, which is a bonus. This was bought at an extremely attractive sale price, as I have seen it elsewhere for double the price I paid for it.I bought this as a replacement item after my first unit didn't survive being dropped into water. The original worked for many years and I expect this to do the same. Keys do get a little sticky but otherwise it's a nice little thing. I use it for temperature measurement of water, marmalade, meat, the oven... anything reallyIt works fine but I’m not happy cuz it does not have an on/off switchCannot recommend this highly enough. Great product and the built in timer comes in very handy.Great gadget getting perfectly cooked meat now !
