RISEMART Digital Calliper 150 mm Electronic Stainless Steel Vernier Caliper with LCD Display with Replacement Battery Measuring Tools for Home and Industrial

As I don’t have anything to scientifically test its accuracy on, I can only assume that this gauge is pretty spot on. It’s so simple to use for measuring internal & externally, and length. It also comes in a useful box to protect it, and spare batteries. Displays measurements in either metric or imperial.

There are a few reviews that criticise these calipers for being plastic. If you work in heavy engineering or regularly throw them down on the workbench, then plastic won't last.I just do light mechanical work on my bikes and the odd spot of DIY around the house. A bike mechanic recommended these to me, ahead of the super expensive, but I do believe, metal, Park Tools. For my needs these calipers are perfect. If they do break they're cheap enough to replace.

Useful to know exact sizes . Not expensive and does the job on that odd occasion you need it.

I use these for 3d printing work, these measure well and aren't too expensive either. Depth measurement is a nice bonus and the calipers overall feel to be of high quality

Mainly made of GRP so quite flexible and will wear. OK for home use but not a professional tool.

I needed this to measure jewellery and use it for other tasks now I have it to hand. Very accurate, can tare if needed. Very sensitive and love the handy case and extra batteries.

Bought this product for my university studies and beyond. This works great, experienced no problems at all. Accurate to 2 decimal places using millimetres. You can't tell by looking at the box, but you can also measure depth with a thin tip at the back. Display is much clearer than the image I attached shows!

Runs down battery when turned off, extremely difficult to get battery out, no indication of orientation of battery or holder. Whole thing made of flimsy plastic. Not worth tuppence.
