  • Accurate, Lightweight, and Easy to Use – Great for DIY and Precision Work!
Model: 6" Plastic
Size: Measures up to 6 inches (150mm) with a resolution of 0.01 inch / 0.1 mm, making it ideal for small, precise measurements in woodworking, jewelry, 3D printing, and more. Function: Offers four measuring modes—inside, outside, depth, and step. The zero reset function and inch/mm conversion button make it super versatile. Value for Money: Very affordable for a digital caliper with this level of accuracy and features. Includes an extra battery and auto shut-off to save power1. Slip Resistance: Made from carbon fiber composite, it’s lightweight and rust-resistant, with a smooth sliding mechanism that doesn’t stick or slip. Design: The large LCD screen is easy to read, even in low light. The slim, ergonomic design makes it comfortable to hold and operate. Cons: Not as durable as stainless steel models—best for light to moderate use. May require recalibration if dropped or used heavily over time. Bottom Line: The SCITOOLS Digital Caliper is a fantastic tool for anyone needing accurate, quick measurements without spending a fortune. It’s user-friendly, reliable, and perfect for hobbyists, students, and professionals alike. ... show more

  • Great For All Around Measurement!
Model: 6" Plastic
You get what you pay for... but in this case. Much more. Looking for a decent, affordable tool for quick QC verification that my entire team could have. Several purchased... Consistent and so far durable. Only displays out one decimal for millimeter measurement, so not the best resolution. But again, for the average home owner (or in my case, quick QC check) they are performing well. ... show more

  • Works excellent for light use (matches the price)
Model: 6" Plastic
This is mostly all plastic, so it’s probably best to get something more heavy-duty if you’re going to be a heavy user. I’m only using it for some occasional 3D print modeling, so between that, the case it comes with, and careful handling I suspect this will last a long time for my use case. It doesn’t feel flimsy or like it will break easily. Has all the features I want and need. Highly accurate and responsive measurements so far. I’ve noticed you can squeeze it with a little pressure when you’re measuring and it might shave off a 10th of a millimeter or so, I suspect that’s the plastic bending a tad, and perhaps that wouldn’t happen with a high end model. For the price, this thing is great. ... show more

  • Cheap but good enough for most jobs
Model: 6" Plastic
It only goes to 1 decimal point for the metric setting but that's all I need for most 3D printing designs and woodworking. If you need more accuracy than that, you'll need to spend more than $8! There is no roller but it slides with a good balance of friction. The plastic that it is made of (the entire thing) seems fairly hard. As long as you are using the calipers correctly you shouldn't have to worry about the plastic getting damaged and affecting your measurements. The only thing I miss the locking nut to keep the calipers in place. Overall, I would definitely recommend to someone on a budget or who wants a cheap second set. ... show more
