Excellent

Excellent! I use one in the sauna because it's one of the few that works at 100C (the display is outside the sauna room, with the sensor going through the wall). I use the other one outside for my childs paddling pool water. I connect them via Zigbee to my Home Assistant. The sensor is very accurate I even measured my body temperature under the tongue with it, and it was spot on :D

Useful for Aquarium and Fridge

Very good for what I need. I use it to check the temperature in my Aquarium with alert that tells me if the temperature is too high and I use also for an old fridge to check the temperature. The only "defect" I find on this product is that the probe is not replaceable; it should be better have it with a 3.5 jack.

Work well but flat cables would be better for fridge/freezer seals

The sensors work quite well. They respond fast and I've never had an issue with them dropping off from home assistant (Z2M). I really like that the main module and screen stays outside of the fridge and freezer (my use case) - that definitely helps signal vs inside the fridge.

My one gripe is that the cables to the probe as non replaceable and round. If they fray, the whole device is e-waste without some hard work probably. I also don't like that the cables are round rather than flat. A flat cable would be more compatible with the door seals of fridges, freezers, and ovens to avoid the leakage of heat/cold.

That being said, I don't think the round one makes a huge difference but it's hard to tell.
