This balance works perfectly. The tare function is intuitive by a sensor. With this function it is easy to make as additive weighed in the preparation of recipes where various ingredients are added sequentially. This same button pressed for 3 seconds will weigh bulky parcels weighing memorizing. The glass top is easy to clean. It uses standard AAA batteries, easy to find and change. The sprinkler will help to make them last. The capacity can weigh up to 15kg everything we want in life. Above 15kg, go to bathroom scales! I recommend this device. I recommend the purchase at Amazon, which, not content with being the cheapest, and quickly book for free, as usual.
