This is the third clock vernier calipers, I have ordered in the past two weeks. I had to proceed in stages, because I did not want to spend equal to 100 if there are comparable quality for less money. So the first step was a noname Clock Caliper for 23, which was re-wrapped immediately after unpacking. Rough processing, very poor fit, stiff, and the measuring jaws were not parallel to one another. The next attempt was the Metrica 10023 for about 43, and for the extra cost I have a much better, though not perfect, quality expected. Right, again next to it. Although quality was better than in the first, but no useful. The processing was still pretty rough, the measuring jaws have great lateral play when closed, plus different thickness at the top. Well, he went back also. Then it's back, looking and reading, which is the next in line. I really wanted to zzl 201101 of birds for about 68. Order delivery, but I have encountered on the Internet on the 1515-100 of Elora. The costs with 10 less (inc. Postage). This stage I did not want to leave. And finally ... the build quality is worlds better than the previous two, light and delicate consistently, feels good. The measuring jaws close perfectly. Let's see how it works in practice. Should notice something with the time, I will add my review accordingly.
