Broke in less than a week.
We got this less than a week ago and the handle is already broken. No one dropped it or hit it with a hammer. It broke being washed in the sink.

Much more than a pizza maker
This is more than a pizza maker. There are 15 different settings that makes this a great air fryer. I will probably not use all of the features but it gives me options for if I choose to. The size was a little surprising because it is bigger than expected, however I just replaced it with my old air fryer. This has great levels of heat, easy to clean and gives alot of versatility.

This thing is AWKWARDLY HUGE but AWESOME!
Let me start by saying that this is not a pizza oven. It's an air fryer that also works as a pizza oven. You can do everything you do with an air fryer here. I'm gonna be honest: This thing is AWKWARDLY HUGE. We spend some time trying to figure out where to put it after realizing the size. You can cook a frozen pizza or a fresh one, with great results. But, again, you'll be able to bake, broil, roast and more. I love it has space enough for chicken wings and vegetables. My air fryer is tiny so this one gives me great advantage. Once you move on from the fact that it's difficult to store in your kitchen, you'll love it. Really easy to use: set timer and press start. After use, you can remove the tray and wash it in the sink. Don't forget to check the instruction manual for recipes and tricks on how to master this thing.

I Love the Typhur Sync wireless meat thermometer
Size: 2 Probes, Size: 2 Probes
I Love the Typhur Sync wireless meat thermometer. I bought it on sale and it is worth the money. It is exactly what I wanted and hoped for in a remote temperature sensor. It also had a little paper that came with it with the factory tested calibrations listed for this unit. I had a chance to do some initial testing with the Typhur Sync yesterday Feb 23rd 2024. I did a little runthough to get acquainted with it using a store bought already cooked Baby Back rack of ribs. Not the best choice as it was already cooked but at $10 from Costco it was ok to sacrifice. And it still turned out good. I Cooked on a Weber Genesis E-330 propane grill and used a smoke tube. In the past I have used this propane gas grill to smoke Ribs, Port Shoulders and Brisket with a Smoke tube. It is possible using one side burner and a Smoke Tube. I had also previously tried smoking with a custom smoker tray from Weber for my grill, which used wood chips, but that was mostly a failure. And I tried a Hot and Cold smoker unit on the back but it had limited success with the heat on. But using a smoke tube and one burner on low you can do an ok smoke on the grill if you can verify your temperatures. What I always struggled with was having faith in the grill hood's thermometer. It turns out the thermometer reads hotter than what the grill temps actually are around the meat! That resulted in an even slower low and slow cook and would not develope bark on pork shoulder. Using the Typher Sync you can see the internal meat temps on 5 spots in the thermometer Probe plus it has one external ambient temperature sensor. So 6 total temps per Probe and you get two Probes! When using the wifi mode it never looses signal. The base unit just should be kept close to the smoker, like 3 to 60 feet or so and it will relay the bluetooth data from the Probes immediately to the wifi so you can use the APP to see your status of the cook. Alternatively you can just use the base with wifi or bluetooth in a manual or smart mode. When I did my test it did a firmware update prior to the start of the cook as it told me one was available to install. That took like 2 minutes since it was already in wifi mode. The firmware version I used was: 100016. From the APP you can configure 1 or 2 Probes for individual use on the same hunk or meat or two separate items on the same or different grills with the same or different cooking parameters. It depends on how you set it up. You choose the meat type and cut and the final temp to reach for that cut with some temperature recomendations that you can adjust. It senses the internal temps from 5 internal sensors and displays an temps of all 5 and an average depending on if you are in Basic mode (white background with less details) or Professional Mode (black background and more details) The Professional mode seems best for me. Seeing all the temps helps to verify that the Probe is placed in a good location. If it is improperly placed some readings may read too hot meaning it is too close to the surface or exposed. So in those cases, reposition the Probe. On a thick peice of meat the cent most sensor will read cooler than the others depending on their distance to the surface. You can use the external sensors to help determin how to position the meet for your cooker or grill. All grills swwm to have hot and cooler areas. If it is cooler on one side or the other, reposition the meat to get it more equal. Or use the cooler side for the thinner end of the meat. This can also be verified by the checking internal temperatures or you can use both probes on the same piece of meat like I did for this rack of ribs which naturally has a thicher end and a thinner end. I have included some of the pictures from the cook with some photos of the base unit and others in the App at various times on the cooking process. The app displays a graph with the target internal ending temperature, The current and past temperatures of each of the 5 interal sensors and the 1 external sensor. Each Probe has its own graph line on the screen. You can slide back and forth between the Probes. You can also go back to the main status screen that shows basic stats of both Probes on one screen at the same time but no graphs or individual sensor readings. It main status screen shows the averaged current reading for internal tempurature, ambiant external temp, target temp and the estimated remaining time before reaching the target tempurature. This is the same as the base unit will display. The Pro version of the app can be selected by toggling the icon in the upper righthand corner. It displays all the same information as the Basic mode and much more. The Pro version displays separate graph lines for each of the 6 temperature sensors. It also displays an outline of the Prope near the top of the display along with the positions of all the sensors in the Probe! You can press one of the temperature sensors locations and it will highlight its graph line. You can further slide your finger around that graph line and it displays the temperature at that position on the line! But the App also warns you that your cook is within 5 minutes of completing with an autible sound if you have your notification sound volume turned up. It also displays a message on top of the current APP screen display. And when you start the cook it will warn that your notification sound is not turned on or up enough. It has messages for each Probe for 5 minute before the cook ends, when the Cook completes, Please remove your food from heat, and Cooking complete after it is done with the 5 minute resting period. It also will remind you that your Probe was not returned to the base unit after a while of sitting in normal room temperatures! Along the way those warnings alert you with a chime sound via your notification sound. It also warns you if your notification sound is turned off when you go to complete the setup of your cook. The base unit will also alert and sound for most of these steps as well. The sound on the base unit will stop when you acknowledge the warning/alert on the App or the unit. The app and base unit also tracks the battery levels of the base unit and both Probes. During the 3 hours I played with it they were at Full the whole time. The App also has a pretty extensive meat setting menu for selecting your type of meat: Beef Pork, Poultry, Lamb, Fish and Other and Manual setting. Other has Venison, Mutton, Kangaroo, Goat and Other! It also lets you select the type of cut for that meat with suggest temps for all cuts. If appropriate it gives you temperature selections for Rare, Medium Rare, Medium, Medium Well, and Well done for most meats. And you can overide any of those to chose your own setting if you like it a bit more or less done. The App also has recipes but there are not currently any taylored for use with a Typhur Sync. But there is also an "Explore" section in the App that had some good articles. Make sure you press the arrow > link to see them all. It has topics like Reverse Sear Steak Temperature and Time, Carryover Cooking: Remove Your Meat at a Lower Temperature than Target, Best Tri Tip Temp: How to Know If Tri Tip is Done, How Long to Grill Chicken Breast Perfectly Juicy and various other guides. The Typhur Sync is a very nice quality unit. It works well and it will be great for keeping track of a longer 10+ hour brisket or shoulder. Or even for shorter cooks in a air fryer or oven or grill where you want a particular internal temperature and do not want to over shoot it by waiting to long on a recheck with a hand held unit. Please see all the photos for better detail. The place where the ambient temperature drops was from opening the grill hood to put some sauce on the ribs and check things. Great Product!
