Mastercraft Vernier Caliper, Imperial/Metric, 3 Way Measuring, Rust Resistant, 3.7¼-in x 2½-in x 3/8-in

This Vernier Caliper is functionally useless. In the fully closed position you can see light through both the inner and outer measurement jaws, the inch measurement is at zero, and the mm measurement is below zero. Therefore there does not exist a single measurement the device can take that will ever be accurate. I will be returning mine, and Canadian Tire should pull these from shelves. Looking at past reviews this has been a persistent issue with the product, reported by consumers for years without being addressed. It is shameful to perpetually peddle an inherently defective product under a house name for such a term.

Wow. I bought the same item many years ago, apparently back when it was worth owning. I used it in one sitting measuring PCBs for a 3D print. That's when I realized it was horribly made. It's extremely sloppy. Pivots 1/2mm easily. It doesn't reall tighten enough to be useful, so if you take a measurement and want to compare it, you essentially have to hold the thing so it doesn't slop around and wind up off by 2-3mm. Next, I wanted to use it to measure exposed threads on coil overs I was adjusting on my vehicle. Surely the lack of precision wouldn't be an issue here. Well, the slider/adjustment knob decided to pop off and fall to the ground. Looked like it was held on by a flimsy piece of spring steel to keep it's tension. Wrong. It should be spring steel, but it's the poorest excuse I've ever seen for it. When I tried to flex it a little to keep more tension, it didn't spring back at all. Slip that back in, I guess. Now it's loose and I have trust issues. I got annoyed again that it was so loose, do I tried to tighten it a little more, and the tightening knob stripped out. I barely turned the thing. So it's sloppy. It doesn't hold a measurement. It's thin and weak. The depth gauge is laughably weak and sloppy. The knobs fell off and stripped out. It's essentially everything that it shouldn't be. I understand that $11 isn't a lot of money, but this product shouldn't exist. Go buy a McDonald's burger and a coffee instead I guess.

This a really good tool for the money. Adjustments are accurate and feel very solid. The ruler is easy to read. Not for super precise work perhaps, but it's more than adequate for what I need.

Durable tool, for a quality price.

Inaccurate, my plastic caliper that I bought for 2 dollars is more accurate than this. Way off by 0.3mm. The scale is not align to zero.
