I have been using plastic for more than 10 years (the body of the electronic filling). Over time, it began to fail when turned on, took it apart several times, cleaned the contacts, but began to lie a lot. The choice fell on this one. I'm not used to the weight yet, the previous one was lighter and smaller. From this I use it more carefully. Constantly, out of habit, I want to press "zero", but when shifting, the reset occurs automatically. I am satisfied with the purchase.
