I recently got two MEATER Plus probes and although I’ve only used them a couple times, I find the meat side of the probe to be very accurate but the ambient end isn’t. I really like the app, easy to use and understand. Although I can’t really complain because they was given to me but if I was buying I would get the block with the four probes and WiFi. MEATER claims the Bluetooth range to be 165’ but it’s not, I’ve done good to get less than 100’.
