Rated 4.9 out of 5 by 15 reviewers.
Rated 5.0 out of 5.0 by Worth every penny I love this caliper. I'd been using a cheap mechanical for years and while it's been accurate, my declining vision led me to this digital. It's of solid construction and easy to read. I'd tell you more,but this horrible HD mobile website erases every other word I write! August 2, 2016
Rated 5.0 out of 5.0 by GREAT INVESTMENT The General Tools 3-Piece Dial Caliper and Marking Set is a great investment. The set consists of a 6 in. caliper and 6 in. ruler (made of stainless steel), and a carbide scriber with magnetic pickup. This caliper set comes in a handsome and sturdy case for storage when not in use. The easy-to-read tri-mode digital display shows inches, millimeters and fractions, which is essential for our company's communications with both our factory vendors and our international customers. The capacity for making inside, outside, depth and step measurements is essential in our processes. We love the fact that there's the auto on/off feature to extend battery life. February 10, 2016
Rated 5.0 out of 5.0 by Nice, quality tool! This is a well made, easy to use and accurate tool. It exceeded my expectations. I was surprised that it came with no instructions but anyone with a little mechanical aptitude can figure it out very quickly. April 26, 2016
Rated 5.0 out of 5.0 by overall great product Very accurate. Because of the fraction capability and the ability to switch between metric and English units, makes this a great product, especially when dimensioning a part and drawing it in a CAD program. June 24, 2013
Rated 5.0 out of 5.0 by Works as expected Worked well, seems accurate (at least best I can tell), and don't see any problems yet. I haven't use it much, but the little I did, I was happy with how it performed. January 26, 2016
Rated 4.0 out of 5.0 by The 8” caliper, works as advertised. It’s an ideal purchase for those of us who like extra precision or don’t see as well as we did in our youth, or both. I love that you can zero the caliper anywhere on the slide, this is very useful for measuring differences, it has saved me some head scratching. I would like if the decimal and fraction functions were displayed at e time, as other devices provide this feature. Also if The Home Depot would ship its orders quicker, most places can get there items out the door in one or two business days. Five business day is a bit excessive and is the main reason I do not order for them more often.. February 10, 2015
Rated 5.0 out of 5.0 by Great product Very nice tool! It appears to be durable and accurate. Nice addition to my tools. April 7, 2015
Rated 5.0 out of 5.0 by This product works very well and is easy to use. This was an excellent purchse. The operation is easy to use for anyone and doesn't require any advanced operational knowledge. Price was a little on the high side but was money well spent. March 27, 2013
