These calipers are compact, sturdy and have a nice weight in your hands. The indented grips are comfortable, the points are precise and sharp, and the angle you set stays in place. It fits comfortably into the carrying clip, which clips nicely to the inside of your white coat. Affordable, indispensable for students and doctors alike, much more stylish, less gaudy than other brands, great value (esp if you happen to lose them)!

Perfect for EKG class for PA school.

I bought a pair of calipers at a local scrub shop and they ended up being crap. I looked and found this pair and obviously bought it. I’m obsessed with these! First of all, I love the little divets that allow your fingers to spread the calipers easily. The tips are sharp enough to stay put on the paper but won’t stab into your hand. The black design is nice. I haven’t used the measuring tool on the side of the case but it’s a nice touch. The clip on the case is amazing. AND MY FAVORITE PART is the magnetic hold in the case that makes sure your calipers don’t fall out and get lost. I’m digging these and hoping they last a long time!

The calipers don't align perfectly, but it is good enough for me. They feel strong and I don't expect them to break quickly.

Does what I need it too!

It helped me in my journey taking my EKG! Helped read the little boxes better to calculate my PR and QRS intervals

I needed these for a class and was shocked at the quality. They are very good quality especially for under $10. The metal is sturdy and the points on the end are sharp and small so I can get pretty precise.

Sturdy, great price, and great for measuing EKGs.
