This is a nice tool, easy to use and accurate. It comes with a sturdy plastic case, instructions, and two extra batteries. The display and printed scales are a good size and easy to read. The dial adjuster makes small, precise measurements simple and easy. Being made of metal ensures it will outlast me. It is definitely worth the cost.

Quite impressed with the value and quality of the product, especially for the fair price! The calipers are sturdy, the adjustment wheel is smooth and firm, the measurements are accurate, and the hold screw keeps your measurement type! It was certainly a change from my previous plastic cheapo, plastic calipers, but I wish that I would've done it sometime ago! These were an incredible step up, and only a small jump in price! The functionality is excellent, keeping your measurements, precise, and easy to use! The product comes cleanly wrapped in a nice box with a sturdy, hard plastic travel, and storage case! They look and feel expensive, while functioning like an expensive set also!

Extremely nice, heavy, all metal caliper. No slip whatsoever so readings are consistently accurate. Locking thumbwheel, open/close thumbwheel, 3 batteries, and sturdy plastic case. Getting a second to swap out garage caliper. Oh, and only $18!!!!

Very high quality, comes in plastic snap case, with extra batteries and takes screwdriver to open and replace metal battery cover. Solid device, has heft, good precision. Feels worth more than ~$20.

I've only used it a few times, but it is very solid and appears to be very accurate. On a personal note, I really like the fractions mode for woodworking.
