Pros:-Best value for the money-Accurate-Easy to use-Lots of applications (smoker, oven, air frier, baking, chilling, etc.)-App works great on iPhone-Comes with 2 probes and air harness for smoker-6(!) total probe ports-Super convenient and makes cooking a breeze-Relay unit has a digital face and beeper, flexibility to use without appCons:-No case for unit and probes, although probes do have a little wrap around plastic piece so they don't get tangledI got this bluetooth thermometer after using a family member's at a cookout they hosted. They had the Weber version. I love cooking and cook 5-6 days out of the week, everything from regular dinners, to fun roasts, grilled steaks, and smoking expensive cuts of meat. But even if you're a novice foodie who just enjoys the occasional smoked brisket or holiday roast, you know you don't want to spend hours of time and lots of $$$ just to have your meal ruined by overcooking or even undercooking the food. This probe offers the reassurance that makes cooking even the most expensive and time consuming meals easy! You don't need to keep opening up your smoker, grill, or oven and checking manually 10 times during a cook, you just kind of set it and forget it. It's a product that makes you love technology!The app is super intuitive and the probe / relay unit works like a charm. Nice thing is you also don't need to use the app outside of setting the temperature if you're inside or within earshot, the relay unit has a nice digital face and a very loud beeper when your food has reached temperature, which most other products don't have. It comes with 2 probes, which is awesome since most other brands only offer 1, and the relay also has 6 probe ports! I don't know what in the world you'd ever need 6 thermometers going at once for, other than maybe 6 steaks on the grill, but even the Weber version only had 4 ports and 1 probe included, unless you pay even more for a more expensive version of their already overpriced product. You do need to turn the sound on your phone on for this though if you're stepping out of earshot, or at least go into the settings of your phone to grant access for the app to ring through the silent mode, so that you can hear the alarm go off. It's also fairly accurate, I have 3 other instant read thermometers and this is within +/-0.5º F of them. I've used this in everything from an air frier, to my convection oven, to a smoker, and even used it to monitor dough when I was making croissants and needed to keep my dough/butter sheet at the perfect temperature, or when I let dough rise and don't want the space I leave it in to get over 80º F.Anyway, I'd highly recommend this product. Other, more known brands are as much as 4X the cost, don't come with more than 1 probe, meaning more money, have limited probe ports, and don't even have a digital face on the relay unit, meaning you HAVE to use the app on your phone and buy other thermometers to use otherwise. Beyond that, the customer service has been stellar! I damaged one of the probes and reached out to BFour directly, and, after I sent them a picture of the probe not working, they sent me TWO new probes without question. I didn't expect that nor did I think they needed to send me anything, I was just hoping they could make a recommendation as to how to repair the probe. Would highly recommend this to anyone for yourself or as an awesome gift!

OK, Here's the scoop...Many of the reviews fuss about the apps requirement for "FULL TIME LOCATION" permission. I agree, that is pretty sketchy. The app will not link to your thermometer at all until you give it FULL TIME location permission. However, once it links for the first time, You can open your app settings and DENY location and the app connects anyway without it. It still throws up the dialog saying it needs permission, but boots up and the dialog disappears at startup.WARNING: I went a bit further into the app settings and found that it also defaults to "Allowed To Use Cell Data In Background"...I also turned that one OFF and the app works great. Why that was there to begin with? All I can say is China is watching???Beyond the initial questioning of possible security issues if installed "as-is", the thing works great.The manufacturer must have improved on its product because it did not ask me for PIN number as many have mentioned in reviews. The instruction booklet has a statement that says :"If your phone keep ask you pin number, please turn off your Bluetooth and open our Grill 5.0 APP, try to connect your thermometer again while your phone's Bluetooth and GPS is on."It says at the TOP of the same page: "Please contact your thermometer with our Grille 5.0 APP. Do not connect your device directly through your Bluetooth. So, FOLLOWING the instructions provided seems to be the key here.The APP works well. Didn't have any issues on first use. Setting temperatures and alarms is pretty straight forward. Just go exploring in the APP to familiarize yourself with what all is available. Some instructions and screen shots come in the instruction booklet, but they don't show everything.I did have a bit of an issue getting the device to show temperatures in Fahrenheit. The instruction booklet makes only BRIEF mention of this by showing the "Temperature" icon and describing it as " °C/°F change and alarm setting". When I clicked the option in the APP, the APP immediately changed from C to F. However, the device continued to display Celsius. After fiddling with it for about 5 minutes, I finally turned off both the APP and the device, Started the APP FIRST, then turned the device on and the device then switched over to Fahrenheit. I have turned both of them back off and on again several times and they are REMAINING on Fahrenheit. So, it looks like it will stay there until you change it back in the APP (Good news for me).ACCURACY: The probes are all within 2 deg. of each other (highest to lowest) when laying side-by-side on the table for several minutes. My wife had an issue with them not reading EXACTLY the same. But, I feel that if 2 degrees is going to make a difference whether you burn a piece of meat, you are WAY too picky!!! I cooked some steak on the "Medium Well" setting and they came out with just a tiny bit of pink in the middle...just the way I like mine! I used my trusty old one-channel thermometer to probe one of the steaks next to one of the new ones. They were within about 4 Deg. of each other for the duration. At times, they were reading exactly the same.So, I have determined that I can pretty much trust this unit to get my meat done to my satisfaction without burning it. After all, is that not the whole point?In conclusion, I love having several probes so I can cook different things on the grille at the same time and watch each of them individually. I agree with other reviews that the requirement for location permissions (and cell phone data use) is not a good thing, but both of these can be turned off without any functional detriment once the phone has made initial contact with the device. The thermometer works perfectly. The accuracy seems very good. The APP is fairly easy to figure out how to use, and I believe this to be a really good value for the price.

Works great as described haven’t had any problems with it batteries have lasted and thermometers are accurate you can use up to six probes at one time and adjust temperature settings on your phone sounds a alarm when it reaches temperature

I bought this item and had an issue with one of the probes. It read ~30 degrees higher than the other probes at room temp. I emailed BFOUR and they replied the next day. One day service! They are sending out replacement probes at no charge. Pretty amazing service!! The unit itself is straight forward to use, and all the other probes are within 1 degree (or less) of each other at room temp. The sender connects with my phone anywhere in my house. Results using this product have been great, delivering medium/rare steaks and prefect pulled pork without error. I recommend this product!

Works as it should. Good quality and accurate I checked it against my analog when I first go it to verify. Easy to setup and use.

Rebaso mis espectativas, buena calidad y funcionamiento, El personal muy TENTO Y ENTREGA EN TIEMPO Y FORMA.

Muy bien para controlar la temperatura a distancia

Fungerar mycket bra, tänk dock på att väggar förkortar räckvidden rejält. Men jämfört med en tidigare bluetoth-termometer är räckvidden mycket bättre (längre)

Strata pieniędzy, używałem go bardzo rzadko a po zaledwie kilkunastu próbach już nie działają prawidłowo 3 z 4 dołączonych sond. Wahania temperatury podawane są zawyżone o ok 20-30stopni

After usingseveral food thermometers over the years this product is the best. Easy to use both for barbeques and indoor ovens.Very versatile and so easy to read display. Excellent App with sevveral programmed cooking times for different foods.Am recommending withoUt reservation.
