Out of the box:Heavy, Slides roughly. The jaws are fairly parallel but not polished (only ground). After trying to adjust the slide tension screws (the two on top side), I didn’t get much improvement, so I figured maybe the protective grease caked up. A good cleaning and polish, the roughly sliding jaw was better but still binds a bit. Found the brass slide bushing bars were not installed correctly. Was better after I fixed my new calipers but still has issues with the fine adjusting block. Turns out it also is not right. I checked the slide for trueness and it’s high right where it binds. So instead of grinding new calipers flat, I tossed in the towel.As a contrast, I have 18†digital Fouler calipers for about 5 years now and they work fine. So I don’t know if it’s a QC issue or what, but I would not recommend the 24†model.I don’t expect to be making repairs or extensive adjustments. Not polishing the business ends is cutting corners. Not taking the time to properly assemble a one moving part assembly, is likewise, cutting corners. Not bothering to de-bur nor polish the slide parts, is also cutting corners. I am sure that the company will say, it douse the job of measurement and I would say, maybe it does but a two foot metal caliper that binds, is not a tool I would use in my shop.Made in China

I needed a 12" calipers for hobby use to measure bicycle crank lengths and such, and for general measuring in other hobbies I have. I had a 6" vernier caliper that I've had for years and it just wasn't long enough for a certain percentage of my measuring needs. I prefer a vernier calipers over the dial or digital calipers for the durability, simplicity, and elegance of a time-proven classic tool.I'm not a professional machinist, but I have an appreciation of fine hand tools and am willing to pay extra for quality tools. I almost universally purchase USA-made tools, and am willing to pay the premium. The Starrett version of this is made in the USA but I just couldn't justify the $200+ price tag for something I might use a few times a year.This Fowler tool fit the bill nicely despite the fact it's made in China. There's no country of origin engraved on it, on purpose I think, but I have to say they made a nice tool. I thought the workmanship was OK with minimal dings or other evidence of mass-production. It functioned perfectly. I don't have any 'standard' to measure, to test its accuracy but then again, as a hobbiest, I won't be doing aerospace-level accuracy work with it. It would be instructing to compare the Starrett to this side-by-side and I suspect the Starrett would come out ahead but at a steep cost, and for no improvement in functionality.I don't see any reason a professional couldn't use this in a day-to-day workplace, but they might prefer a dial model.It comes covered in light oil, in a plastic wrapper in the wooden carrying case. A little bit of Windex on a cloth got it ready for use. The wooden carrying case it comes in is really flimsy but you could reinforce it a bit if you wanted to with minimal effort.The website description of this calipers, which is model #52-085-012 is actually incorrect The "085" series of vernier calipers does NOT have a depth gauge capability, whereas the slightly more expensive "058" series does. I actually would have preferred the "058" series calipers but I couldn't find one in the price range I paid.I got mine new on ebay from one of the mass on-line retailers for $46. It wasn't listed as a Fowler instrument, and you had to look carefully at the picture to see the manufacturer's name on it.
