The only flaws are a startup may be slower than the others, wait 5 seconds when turned on. And we can not remove biiiip when pressing the keys. Nothing serious ...
The most important is that the temperature displayed is accurate and does not fluctuate at all measures.
Otherwise side disposable tips, I bought a refill box at the same time (it is not very expensive) but frankly I think we can keep the tips included with the device and wipe with a handkerchief each measure, provided that the thermometer remains in the same family! Hygiene oblige!
