Query: Great Scale - Purchased a Second One for Work

I loved this scale when I purchased my first one about three years ago! It is so versatile and easy to use. The Tare and Units functions are self-explanatory. I use it to help me pack my backpacks and assess if the extra weight of an object is worth packing. I also find it extremely helpful in the kitchen. The battery life is fantastic! I am glad I did not bother with purchasing an AC adapter--the freedom to move the scale without the need for an AC power receptacle is so great.
