I see what you mean. It's OK if you can remove them from the job without disturbing the first reading, but often that isn't easy.
My Aldi ones all seem to "remember", but a set I got from Lidl (I think) are like yours. However, the read head on a recent Aldi set didn't move very smoothly until I stoned down the beam very lightly.
To get back to the topic, my big Record bench vice, if you can call it a machine, is annoying me at present. Once clamped up, it sticks on, and needs 10 degrees or so CCW on the handle before it releases with a bit of a jerk. This can get irksome when I want to relax the grip just a little, to adjust the position of something heavy. I've cleaned and lubed it, but that seems to have made no difference.
And then there's an old pair of tin shears, where the ends of the handles bend in sharply to within 1/4" of each other when closed. If I use them to cut material which is a bit beyond their capacity, squeezing valiantly with both hands and going purple in the face, the handles can painfully pinch my ample abdomen when the material suddenly yields, causing a colourful bruise. I need to slim, though cutting the bends off the handles might be easier.
