Themisto TH-M61 Digital Vernier Calliper (0-150MM/6")

⭐⭐⭐⭐⭐ Accurate, Easy to Use, and Great Value I purchased this Themisto Digital Vernier Caliper for measuring 3D printing parts and small mechanical components, and it has exceeded my expectations. The display is clear and easy to read, and switching between millimeters and inches is quick and convenient. The caliper feels sturdy, slides smoothly, and provides consistent measurements. I also appreciate that it comes with a protective storage case, spare battery, and user guide, making it ready to use right out of the box. The zero-reset function works perfectly, and the measuring accuracy is more than sufficient for hobby, workshop, DIY, and engineering applications. For the price, this is an excellent tool that offers professional-level functionality. Highly recommended for anyone who needs precise measurements without spending a fortune.

Good Product, Build Quality, Economical, Accuracy, Durable, Easy to Use.

The tool is quite good; sometimes the calibration gets off by 0.01 mm when the mouth is closed, but after calibration, it works fine again. The slide is not loose but sturdy, and the maximum reading is around 155 mm. The display is also clear. I also received a cell and a screwdriver inside the box.

Awesome quality, used for a week or so and it's been a pleasant experience so far, was suprised that even the housing of the electronics or measuring part or whatever its called is also made of metal, so yeah good quality worth the price

Good product 👍

Nice product

This instrument is a marvel within the price range. The entire body is of hardened S.S., even the operating buttons. The facia and the cover of the battery compartment is of good PVC material. Accuracy is definitely within the tolerance limit. Crispy and clear display. I definitely recommend this beautiful product, for others to purchase.

Don't waste your cash on this. I've used this Themisto digital vernier caliper for over 6 months and it's been a disappointment from week one. What you're actually buying: a generic Chinese caliper with "Themisto" stamped on it. There's nothing proprietary, nothing engineered, nothing that justifies the brand markup. Same thing sells for half the price on AliExpress without the sticker. Two dealbreakers: 1. Inconsistent accuracy. - Measure the same object three times, get three different readings. For a measuring tool, that's not a flaw — that's a failure of the entire purpose of the product. I can't trust a single number it comes up with. 2. The OFF button is a lie. - Press it, the display goes blank for 5-6 seconds, and then it switches itself right back on. So even when the caliper is sitting in my drawer untouched, it's silently chewing through the battery. I've replaced batteries at an absurd rate because there is no actual way to power this thing down. Whether that's broken firmware, a faulty circuit, or just lazy design — it doesn't matter. The product literally cannot be turned off. Build quality is cheap plastic, the jaws have play in them, and the slider doesn't glide smoothly. For precision work, this is unusable. For rough hobby measurements, you're still better off with a manual caliper that doesn't lie to you and doesn't eat batteries while it sleeps.
