Non-contact K3 Wall Mounted Infrared Temperature Measurement Forehead Thermometer with Alarm for Office Home Supermarket Subway School Community (no battery included) use 18650 li-ion battery flat top

This did not come with a battery or charger just a small USB cable. Can someone tell snd link me to the battery it is suppose to use so I can get it??

Advantages: fast test results. If the safe temperature is exceeded, the alarm will last for a long time. It supports sticking on the wall, wall mount and tripod (need to be purchased separately), supports switching between Fahrenheit and Celsius, and can be powered by AC or battery.Disadvantages: Just received the goods, the price was reduced from 84.88 US dollars to 79.98 US dollars. Later, I found that many other k3 models cost about $50. The actual product, workmanship and quality are not worth $84.88 at all, maybe during the COVID-19 epidemic, the price is so high? Does not include AC power plug and battery. To install the battery, you need to remove the three screws and the back cover to install the battery, which is very troublesome. The switch between Fahrenheit and Celsius is too concealed and there is no obvious prompt. If you do not read the description, you will not know its location. There is no indication on the Fahrenheit and Celsius temperature display panel. You will not know the current temperature.

I install it for my company for all the employees will have their temperature checked before they can punch in, thank you so much this is a great product.

Excellent purchase, highly recommended. I have it at the entrance of my house so that my guests can check their temperature before socializing in my house. A little trick to switch from C to F, there is a small hole in the back that you can stick a toothpick in and switch it without downloading the software.

Very fast scanning. Runs off USB cable or some weird size batteries. Alarms and flashes red lights when person is over A set limit temp. Single beep and green light for normal temp. Has threaded slot in bottom for Tripod mounting.

Useful tool considering we're dealing with Covid-19. It seems to work well most of the time, but it's not always accurate.

This product is ok functionality however it desperately needs to be calibrated. Measures 5 to 10 degrees cooler. Not impressed.

I own a music studio. For the pandemic we set this outside to take everyone’s temp. Before coming in. It is accurate and quick. (We’ve only used it for workers so far as we haven’t opened yet.)
