Caliper Measuring Tool, Qfun Vernier Digital Caliper Stainless Steel 6 Inch/150mm, Digital Micrometer Waterproof, Easy Switch from Inch to Millimeter, Large LCD Screen

UPDATE 2/11/26- As it turns out, a low battery seems to have been causing the random readings and instability. I would not have expected that but wanted to set the record straight. It is back to functioning as designed with a new battery. If you have a similar problem (mentioned below) try changing the battery. Original review: I used it a few times when I first got it and it seemed fine, but the last few times the display bounces around random numbers and segments of the digits are missing. Even if they did show fully the values aren’t right. I’m forced to use the printed scale on the stem and do my best at precision. Wouldn’t buy this again.

Easy to use and accurate. Fair price and even comes with its own case.

i've had this caliper for years, but used only a half dozen times; had to replace the battery almost every time. when it died i bought the same unit again since it was only $20. i found the new caliper had the same excellent build, and came with an extra battery; however the case was replaced with a cheaper version. fortunately i kept the previous, foam padded case which fits perfectly. 5 stars for the build 5 stars for easily used features 5 stars for the price 4 stars for having to remove the battery after each use.

I bought this Caliper Measuring Tool specifically to measure inline skate wheels, and it works perfectly! The measurements are precise and easy to read, making it a breeze to get the exact wheel measurement. Beyond just inline skate wheels, I can already see how useful this tool will be for other tasks around the house and in my workshop, like measuring small parts, bolts, and other components that require accuracy. The build quality is solid, and it’s a versatile tool that’s great to have on hand. I’m very happy with this purchase and highly recommend it for anyone who needs a reliable and precise measuring tool!

At it's price, I was somewhat skeptical about how well this caliper would actually work. I was most pleasantly surprised. It is very and repeatably accurate, easy to use and read, has mm/asa selection, well made, and automatically turns off it no in use for long battery life. Overall, a great value. This travel case is "just right" and the quality is way above what I expected. I was surprised. Yes, it does fit under a airplane seat. ( at least the Boeing 737 series) except the row directly behind 1st class seating. Acid Test: Would I buy this again if needed? Absolutely.

Great caliper , very precise and easy to use. Would recommend to anyone with use of it

Bought two and they both started freaking out for no good reason. Probably because they just sit there draining the battery all day, despite sitting unused. Absolute garbage, going to spend extra money on something that will work for longer than six months.

Works great and amazing price. Ordered this so I can measure watch measurements / strap measurements. Total of 3 measuring functions. Easy to use.

He tenido varios calibres pero nunca ninguno con medidor digital. La verdad es que es muy buen calibre y tiene una relación calidad precio a mi parecer muy buena. Cuenta con una pantalla grande y una precisión de 2 decimales, más que suficiente para alguien que no es un profesional y no necesita una precisión extrema. Cuenta con una rueda para afinar mejor la medida y otra rueda para fijar la medida y poder llevarnos el calibre con la medida tomada por si no lo vemos o deseamos compararlo con otra pieza. Un detalle que me ha gustado mucho es que incluye una pila LR44 a 1.5V, la cual viene ya puesta en el calibre y otra de repuesto. Esto es un detalle que ayuda mucho para darle las 5 estrellas. El calibre se apaga desde el botón de on/off pero para encenderlo, basta con abrirlo y el solo se enciende. También cuenta con un botón de puesta a 0 por si fuera necesario re-calibrarlo o ponerlo a 0 en otra posición que no fuera cerrado. La amplitud máxima del calibre considero que es suficiente, es estándar de 150mm Otra cosa a destacar es que viene en un estuche de plástico para que no se ensucie y poder guardarlo y alargar su vida útil. En conclusión gracias a su construcción en acero inoxidable y a las prestaciones mencionadas anteriormente, considero que es un producto muy recomendable.

Als begeisterter DIY'ler bin ich stets auf der Suche nach Werkzeugen, die sowohl präzise als auch erschwinglich sind. Der digitale Messschiebe, erfüllt diese Anforderungen perfekt und hat meine Erwartungen übertroffen. Zunächst einmal beeindruckt mich die Präzision dieses Messschiebers. Trotz seines erschwinglichen Preises liefert er genaue Messergebnisse, die für die meisten DIY-Projekte mehr als ausreichend sind. Ich habe ihn bereits für verschiedene Aufgaben verwendet, von Holzbearbeitung über die Planung von Ersatzteilen mit CAD Programmen für den 3d Druck bis hin zur Metallbearbeitung, und war jedes Mal mit den Ergebnissen zufrieden. Die Bedienung des Messschiebers ist ebenfalls sehr einfach. Das gut ablesbare LCD-Display zeigt die Messwerte deutlich an, und die Bedienelemente sind intuitiv angeordnet. Auch das Umschalten zwischen metrischen und imperialen Einheiten funktioniert reibungslos. Die Qualität und Haltbarkeit des Messschiebers haben mich ebenfalls überzeugt. Er liegt gut in der Hand und fühlt sich robust an, was wichtig ist, wenn man ihn häufig verwendet. Außerdem wird er mit einer Schutzhülle geliefert, die ihn vor Staub und Schmutz schützt, wenn er nicht in Gebrauch ist. Einziger Negativpunkt ist, dass er ab und zu bereits in der Schutzhülle an ist, da sich der Knopf hierfür sehr leicht drücken lässt. Insgesamt kann ich den digitalen Messschieber jedem Heimwerker empfehlen, der auf der Suche nach einem präzisen und dennoch erschwinglichen Messwerkzeug ist. Er hat sich als äußerst nützlich erwiesen und ist ein unverzichtbarer Bestandteil meiner Werkzeugkiste geworden.

Très précis. Cadran très agréable

Ho acquistato il calibro digitale Qfun per piccoli lavori di precisione in ambito hobbistico e meccanico, e sono rimasto davvero colpito dalla qualità del prodotto. Realizzato in acciaio inox, il calibro trasmette subito una sensazione di solidità e resistenza, elementi fondamentali per uno strumento di misurazione. L’ampio display LCD è uno dei suoi punti di forza: leggibile anche in condizioni di scarsa luce, rende la lettura immediata e senza errori. Le misurazioni sono rapide e precise, con la possibilità di passare facilmente da millimetri a pollici premendo un solo pulsante. Ho testato la precisione sia per misure interne, esterne, di profondità e passo, e il risultato è sempre stato affidabile. Altro punto a favore è la funzione di azzeramento in qualsiasi posizione, molto utile quando si devono fare misurazioni relative. Inoltre, lo spegnimento automatico aiuta a preservare la durata della batteria. Nel complesso, si tratta di un ottimo rapporto qualità-prezzo, adatto sia per professionisti che per appassionati del fai-da-te. Se stai cercando un calibro digitale preciso, robusto e facile da usare, questo modello della Qfun è sicuramente una scelta consigliata.
