All three work fine for me and all read the same value, which is impressive considering the claimed specs. There might be an issue with battery life when you receive them as the modules are already running straight out of the box. So, depending on how long they have been in storage, the cells will be run down. This could explain the varied reviews. Also the display is set to update with a short interval, possibly 2 seconds or less this would shorten the battery life to some extent. I did open one of them and there does seem to be the option to change the update period, but have not found anyone playing with these on the web so have left them alone for now, they work! Review: How accurate are the thermometers, and are batteries included? Are they useful? - Having seen numerous reviews saying that contrary to usual practice when batteries are ready fitted, these thermometers come without the pull-out plastic tabs so the batteries have been running down since they were fitted. In anticipation of this, I also bought a pack of 10 batteries. I checked the ready fitted batteries before fitting them to the measuring points, and found two gave 1.4v and the other 1.3v. The units themselves are fine, and the three in the box all showed the same temperature, and were within half a degree when checked against our other thermometers. They did exactly what I needed them to do, which was to check and adjust the running temperatures of a multizone heating system with underfloor downstairs and radiators upstairs. The units respond very quickly to temperature changes with clear easy to read displays. The unit with the 1.3v reading lasted 24 hours before switching off, at which point I changed batteries in all three units. Changing the batteries takes about 30 seconds, and the build quality is perfectly acceptable. I used cable ties to fix the sensors directly to the pipes, and mounted the display units on top of various control units in the control cabinet and can now see the input and output running temperatures at a glance. Even if they don't last for long, they've already earned their keep, and as they are so easy to use, I could easily move them to use elsewhere. They are not precision scientific instruments, but sufficiently accurate for my needs and much better than I expected for the price. ## Features - Simple and elegant design, LCD display, moisture-proof, strong anti-interference.

I cut my fridge door to flush mount them, but don't do it on a freezer door. Very accurate. **Q: How long is the wire?** A: Hi the wire is about a 1 mtr long and they work very well **Q: Are there any settings with this thermometer or is it just plugged in and ready? Mine just says 'Hi' if there are settings, any idea how they're set?** A: Hi..it seems that there are no settings it just works....lol **Q: Will they work as room thermometers** A: Yep ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent thermometers *by J***E on 29 June 2023* Some of the reviews for these modules nearly put me off buying these!
