Surprise at the reception: it does not at all correspond to the picture presented, but on the box it is the right reference. Before returning, I think I'll test it anyway: 1) material quality is OK but not great. 2) the adjustment of two heads: it's good. 3) games: a) there is very average, sliding side is not very fluid (but better that than too many games): we will put a little oil, it is a little better and it will take place with a long break (there is the small screws on top to adjust if necessary) so that's good, b) lateral play, it's just blah in acceptable. 4) the dial: it is as it should be (not like the picture) 0.02 to 0.02 with ironing by half turn to 0 mm for even and odd. 5) most important: measures: a lot of tests done and a very correct repeatability since it is mechanical, not digital: occasionally return to zero has changed little in 0.01 (small readjusting the dial ) but it seems to me still very good. In conclusion: disappointed at first because I was expecting the best quality but I will keep because, for a price of about 30, he still want good measure and that this is the main thing. But it is not worth more, around 30 is a maximum, it is currently 49 on the site and this is far too expensive for what it is ...
