MARATHONVernier Caliper, Lightweight Durable Plastic. 0-6 inch (150mm) Scale Range. (Grey - Single Unit)

This is a vernier caliper, just not a high precision one. Where a "real" (metal, expensive) tool has an adjustment wheel, this on has a plastic nub. No problem, I knew that when I bought it. I only wanted 0.1 mm accuracy and this delivers at least to that level. This is a good, casual caliper for around the house and many workshops. It's not an expensive super high-precision (0.001mm) tool.I chose this model specifically because I need to measure watch parts, and I wanted something that would not scratch cases or crystals.This is perfect for what I need, and at a very good price. I recommend it, for this price point.

This caliper is perfect for casual use. Of course it's not a precision caliper for measuring to 0.001", but for many things it's just what's needed. I have a lot of fancy expensive precision calipers, but I use plastic ones to keep in the garage, in the shed, in the car for those trips to Home Depot. They're really handy and you can't beat the price. Don't be fooled by the cheaper ones that are made in China and sell for 5 for $7.95. Those are junk. This one is made in Canada and is good.

The zero point is off by around 1mm. It's a waste of money for me. At least it wasn't $$$. I have other inexpensive calipers that are far better at zeroing.

Very simple, yet very effective. I bought this set of calipers for measuring a few watch crystals that I wanted to replace. I've come to appreciate just how useful these are around the house.

The first one I got had to be opened about 1mm to set to zero. It was also shipped in a soft package and got bent during shipping. I sent it back.I got the replacement very quickly which was also shipped in a soft package but was not damaged. In trying it out the metric and standard measurements don't coincide. Not too good.

The scale on this goes out to 7", but can only measure 5-15/16". There are other less expensive callipers out there that do just as good a job. Not impressed.

It's pretty good plastic caliper. It is perfect for my use.

They work for non critical measurements just fine.
