Spedizione rapida e precisa. Ottimo rapporto qualità-prezzo. Soddisfatto.

la precisión es buena por ahora, lo único que si aprietas mas una vez q otra t puede poner una diferencia de 0.01 por lo que se puede cuadrar perfectamente

I still refuse to believe that this thing cost only a couple of pounds delivered. Has to be the measurement tool bargain of the century!QUALITY:According to the other reviews the quality may vary, but I must have been lucky and got a good sample. Overall finish is perfect, spindle has no wobble, thimble turns very lightly and smoothly (as long as the spindle lock is fully released... I'm still learning!), and rachet stop works perfectly. Free tip: Check wikipedia for great explanation of micrometer parts.ACCURACY:I needed this micrometer for a valve clearance job on my car, to measure the exact thicknesses of valve shims. The measurement range will be small, 4.25mm is the thickest shim available. I tested the accuracy by measuring thicknesses of single feeler gauge blades, or combinations of blades.All single blade (0.05mm to 1.00mm) measurements were accurate, micrometer showing +0.002mm to +0.003mm per blade, which I find a very good result for a micrometer costing well under 10 pounds.When measuring thicknesses of several blades together, the rachet stopped a bit too early, giving too high a reading. I presume this is more of an issue with me measuring several blades together rather than with the micrometer. This cannot really be avoided as the blades would need to sit completely flush with each other for the measurement to be accurate. When tightened a bit further with the thimble until tightness was about right (no gaps between blades and started feeling a bit more resistance), the reading was again off by just a couple of thousandths of mm.All in all, knowing that the micrometer reading is a tiny fraction too high but tne amount is constant, I can adjust my readings to get the exact thicknesses of shims down to just 0.001mm to 0.002mm - in other words, this super cheap micrometer will do its job nicely!ACCESSORIES:The micrometer came inside a plastic box. It will protect it from elements, but it only has some very thin padding inside. It could have had a bit more padding to stop the micrometer from moving.Also included was a calibration tool.There was no manual included. A small A4 size manual with descriptions of micrometer parts and how to use it, calibrate it and take care of it would have been nice. Luckily, there's internet.PRICE AND DELIVERY:What can I say. Seven quid with free next day delivery with Amazon Prime.

J'ai mis 5 étoiles non pas pour la qualité absolue de cet outil, mais pour son rapport qualité prix. Je l'ai acheté pour mesurer l’usure des disques de feins sur mes voitures et éviter les échanges beaucoup trop fréquents si on écoute les "spécialistes". Il est livré en coffret pastique résistant moussé à l'intérieur. La glisse du tambour est parfaite, l'aspect visuel est très correct la précision est à 1.5 centièmes de millimètres. Le zéro est apparemment réglable au moyen d'une clé (fournie), je n'ai pas encore essayé. L’équivalent de cet outil en grande maque d'outillages vaut environ 12 fois plus cher mais n'est évidemment pas 12 fois meilleure. Comme la différence de prix se justifie quelque part, le mieux est de lubrifier cet outil à l'huile d'armes et au chiffon pour le garder longtemps sans oxydation, il en vaut la peine.Pour des travaux de mesure à plus de 3 centièmes, je recommande sans hésiter.

Die Messschraube kam sauber verpackt bei mir an. Eine Kalibrierung war nicht notwendig, auch befanden sich keine Fettrückstände oder ähnliches auf den Oberflächen. Für meine Zwecke (hin und wieder die Dicke der Bremsscheiben am Motorrad/Fahrrad vermessen) reicht das Gerät völlig aus.
