This caliper worked well until it suddenly fell apart about 5 months after purchase. I don't know how but the bushing that allowed it to slide with little friction fell out causing it to just open fully and fall apart when I picked it up one day. Mind you, they still work, but the sliding mechanism is outdated. There's almost no friction, so you have to actively apply pressure to get an accurate reading of what you're measuring, and now it falls apart quite easily.
