Seems accurate enough though hard to test. The display easy to read.Unnessary 'blinking' display when reading Max or Min temperature values. Why??Fiddly process to read Max & Min values - have to press 'Inside' or separate 'outside' button to cycle through the Max, Min and Current temperatures - but every similar unit seems to use the same kind of system.The MAJOR problem - and hence the 3 stars for 'Ease of use' is that there is no way to reset the Max and Min values without removing the battery - there is no 'Reset' button.How simple would it have been to include one - even if it was a simple push switch which is 'push to break' (i.e. a 'normally closed' push switch) so that it disconnected the battery temporarily. We're not talking rocket science here!Overall, a good prduct and a similar price to others. I like being able to see both the inside and outside maximum, minimum and current temperatures but the omission of a simple reset switch is quite unforgivable.Recommended with reservations.UPDATE:I added a crude 'reset' switch as follows.1) Remove the external temperature probe and battery2) carefully remove the yellow front screen (it is self-adhesive) and remove the four tiny cross-head screws in order to separate the two halves.3) carefully solder very fine insulated wire to the solder pads each end of the battery connectors4) feed these through the small central hole in the back5) solder these wires to a small 'push to make' (otherwise known as a 'normally open) push switch(I used a 'Tact Switch Wafer Thin SMD GOLD MICROSWITCH Tactile Push Button 4x4x0.8mm' from a well-known auction website)6) replace the bottom cover, the four small screws, the yellow front screen and the battery.Now, when you press the button, it shorts the battery (meaning zero volts to the thermometer) and 'Hey-presto!' the thermometer is reset. Just needs a very shork 'click' press to do the job.Hope this hack helps! ### ⭐⭐⭐⭐⭐ good design *by M***E on 18 December 2018* I like the design,it is very useful and display is convenient and funny.Product is simply and easy to use,but also practical.Good value for money.Definitely recommend. ### ⭐⭐⭐⭐⭐ Juist great *by T***S on 23 February 2017* First class item - details very clear.
