Works well! Bought another one!
Accurate and easy to use when checking RV refrigerator and ice chest temperatures. A little slow reaching new temperatures but a great peace of mind.

GREAT THERMOMETER
IT DOES A GREAT JOB WITH MY CHEST FREEZER. I KNOW THAT IT IS WORKING BY JUST LOOKING AT THE THERMOMETER.

Peace of mind
Love this as used for registering my crawl space temp. It gives me peace of mind when the temp drops as I know without a doubt if the water pipes are in danger of bursting. There is no off switch so the battery has to be replaced/removed after every use but shows large digit numbers in Centigrade or Fahrenheit.

No "Off" Button!
There’s no Off button! How do you turn this off? It runs on battery, and I don’t need it on 24/7 In fairness to this product and the company I needed to upgrade this review from a 1-Star to a 4-Star. Here's why: I use this thermometer to gauge water temperature while thawing food for my snake. It only gets used once a month. Since I bought this product it has worked as expected and accurately. Yes, it's always on and on my kitchen counter by the sink. The bottom line is that it works—it works exactly as described. The batteries are still the original, so they last a long time. I find myself looking at this thermometer while in the kitchen to get the room temperature. I upgraded it to a 4-Star because it works, but I lowered it from five because it would be a full 5-Star if it had an on/off switch like my other top-brand digital thermometers.

Works great in our camper refrigerator
Purchased to keep track of temps in our camper refrigerator - easy to put above refrigerator to enable us to check the temps without continually opening the door to check. Seems accurate, quality is good, bright enough to see easily and very pleased.

Disappointed
We ordered the HATUSOKU Digital Thermometer believing that the product was manufactured in Japan. I also expected that with a MIN/MAX feature, those values could be set by consumer. WRONG on both accounts. The MIN/MAX feature of this product appears to be that it is a preset internal calculation that relies on the current measured temperature. What good is that? To what purpose is it to see arbitrary values displayed that have no relevance? More importantly, the included literature is concise as far as manipulating the device but inaccurate in that the MIN/MAX option is dependent upon the probe's currently recorded temperature & a predetermined calculation. I can find NO option for setting the MIN/MAX values manually and I might just want more than a 3-to-4 degree range between minimum and maximum temperatures. So, what did I get for my money? I basically received a temperature probe attached by cable to an external digital display head that can display either English or Metric temperature scale readings. The probe cable is run between the door sealant strips but can allow cold air to escape. The loss of cold air from a sealed system increases operational costs while diminishing efficiency of the operation. The electronics can add and subtract a couple of degrees from recorded temp & display those calculations as a "minimum" and "maximum" value, but, again, where and what is the relevance of those calculated values? I mean, unless the product has an alarm mechanism that initiates when the temp exceeds either the MIN or MAX value, the feature is pointless, right? Oh well, at least it gives me a relatively accurate temperature reading. Three stars for functioning correctly as a thermometer.

Good for the money
Arrived earlie than promised. Put the battery in and it immediately started working. Compared it with other digital thermometers and the reading was within limits. So far so good. Will have to wait a while to see if it holds up.

Instructions very clear. OK, as a monitor. Simple to use. I believe the advert gave the impression, min max temp was settable....giving alert. Sorry to see it does not. Looks well with clear display. Used in my garage, to monitor low temps and so boiler frost protection. Not able to add a photo???

These are great - I ordered a second one. Will probably get a 3rd too as so handy. Great temperature readings for fridge thermometer or even a freezer thermometer or room temperature reader
