I bought this in order to compare it to my current wifi thermometer. I really liked the fact it came with 6 probes and had wifi connectivity. And since it was on prime day special the price was right. Out of the box the unit looked nice, but felt a little cheap. It's light and doesn't have a quality feel to it honestly. I downloaded the app and had to search to find which option as it's not a labeled item. You have to use the wifi probe in the kitchen category. After getting it connected which was fairly simple I went on to testing the probes. All the probes read fairly close once connected, with one probe reading a bit lower then the others. Then I did the ice water test and this is were I have a problem. The accuracy is stated at +/- 1degree. However as you can see from the photos they are way off. And the other thing I found is that no matter which probe I plugged in to port 1 it always reads the same. Even when it read different in another port. Secondly the app and the display don't match for some reason. Even after letting it sit for a few minutes to recalculate it never matched. Overall I just don't feel confident in this thermometer and at the current price I would look at others for a better experience.Calibration is a little bit off but I'm hoping it's user error I will try again just to make sureFirst off if it is going to be this difficult to setup then have a YouTube Video or something on it. Also I followed both instructional methods to pair the device to your Wifi or Bluetooth and it doesn't work. The device won't pair to my wifi even after switching it to the 2g version like it says. Spent the better part of Two hours trying to get it to work and no luck. It reads the temps extremely accurate but if I can't check it on my phone or have a secondary relay device inside there is no reason to have it. I might as well just stick with my Thermopen and manually check it.Stopped working after 1 month. Powers off whenever it feels like it on a full charge.I bought 2. Returned them both and only got credit for 1. Would not hook up to my WiFi.Complicated to set up and then didn’t work.Sent it back.My unit works great as afar as I can tell. I already had the app on my phone from another device, and this connected right up with no issues. I've used several of the ports and had better grilling experiences than by simply timing and managing the heat - no more guesswork. It seems to be accurate to me as everything I've used these for has been cooked to perfection following guidelines for doneness that I find on the web. I've not tested it in any other way. To me, this is for cooking; be that on the grill, the stovetop, or in the oven and it seems silly to me to criticize it for readings in ice or cold water - I would never use it this way. I did read one user who wanted ranges - I would suggest setting at least one extra probe for your high point so that you know you've reached your max - as a work-around that would at least let you know when you've exceeded your limit and need to back off some. With this number of probes some sort of cable management would be nice, but otherwise, I'm quite happy.This has so far proven to be a great product. I love to make chicken entrees but I don't make them as often as I would like because I'm always afraid they are under cooked in the middle, especially when frying. This will no longer be an issue for me! For the first time, I fried chicken using this thermometer to gauge when I could officially take the pieces out of the oil and we had a perfectly cooked meal! Every other time I've fried, I had to open them up to check the center. More often than not I would have to cook them longer which then made them a bit chewy because I had cut into them. Never again! We used the thermometer on each piece and knew exactly when we could take them out! I gave this 4 stars on ease of use because it was a bit of a pain to get set up. To be fair, I should have taken everything out of the box and read it all a day or two before actually trying to use it because you have to download an app which took a little longer than I thought on the set up. The reader also has to charge for 12 hours, so this is not a contraption you can open up and get right to work with. Needless to say, my family had fried chicken two days in row because I couldn't use it that first night, but it gave me the ability to compare how different it was using my old thermometer which wasn't reading exactly right (hence the sometimes pink chicken) and this one. Once we understood all of the directions and got everything charged up, this was a beauty! Extremely accurate and we have been able to get perfectly cooked meat every time so far! My husband loves to grill and in our family of five we have to cook to a medium, medium-well, and well done palate to satisfy everyone which makes this gadget a grillers dream come true. I must also say that I was very impressed with the seller who reached out through email to make sure that I received the item and ask if we were having any issues- which it's always nice to know that a company is interested in providing good customer service even when there is no complaint. I would highly recommend this and I hope it is useful to us for years to come-but so far so good!
