In practice it is very convenient, thanks to the automatic tare function. She's very precise air (I tested with weights rocking balance, and the weight of 1g to 200g indicated was always right, even if the weights were in the middle)
The AAA batteries that are found everywhere are a big plus. No need to look for a button battery unaffordable and unobtainable.
The tray is large enough, and you can ask large bowls without any risk of spilling.
I have not enough experience but the 5-year warranty offered suggests to me a fairly high reliability.
