These are three different size goniometers. There is not much to be said about them. They work as expected and as intended. I use them in drawing and illustrations to draw lines at particular angles and to draw circles. I find them to be much more useful that having to use several instruments (protractor, ruler, compas). They are also thin and fit easily on the page without interfering with the edges or binding.

This is a nice affordable set of compasses designed for Physical therapy, but I am a woodworker and have use for these in my shop. Some times tools cross trades. Having a clear compass to overlay and check angles is handy and these fit the bill. The only downside is the two smaller ones are crystal clear but the larger one the used a different plastic which though it is translucent, it isn't as clear as the other two to see through which is why I purchased these. But they all work well and give reference when you are looking for estimated angles.

With some joint and mobility issues, a family member got instructed to start with stretches. We used these to check in on progress, which was extremely motivating. Recommended to help relatives after joint surgery and the painful process of physical therapy and recovery - one can measure the success...

Well I'm not using these for medical purposes,. I'm using them for drafting and woodworking, they can easily draw circles of various sizes on boards faster than a compass.. sofar I've found them very helpful for that purpose and I guess if I ever need to measure the movement of my joints I'll already have something on hand lol.Besides using them for things like I am,. I believe they will work properly for there original intent aswell... while I was going to physical therapy my doctor used a few tools identical to these on me,.. this set seems to be built of stronger plastic than his were.

I'm going to be using these to align a folded optical system. These are a good alternative to small protractors, easy to align with the apparent optical axis. Everything seems quite accurate - registration of printing vs punched holes.

I'm not sure that I needed three different sizes -- two would have sufficed to cover the range. Be that as it may, the three goniometers do work well for measuring angles to half a degree of precision. I use them for measuring course angles on charts and maps and also measure angles in the shop. The two small ones are clear plastic. The largest one is soft a frosted plastic. This does interfere to a degree with being able to read the angle clearly. One thing that would improve these goniometers would be the addition of one or more pencil holes. With this addition, these goniometers would be useful for marking angles as well as measuring them. (I may modify mine to add this feature. Should be easy enough to do.)

They’re pretty standard goniometers. As they get smaller, the plastic gets appropriately thinner, but they seem sturdy enough to stand up to everyday wear. The printing is nice and clear on all of them. My middle-aged eyes struggle a little with the smallest one, simply because the printing is so small, but still quite clear. The outer red arc, has a zero-to-ninety scale, the inner red arc has a 180-360 scale. The arms all have a ruler in inches and centimeters. There is no logo on any of them.There is enough tension in the hubs of them to hold a position once you measure. Yes, technically you’re supposed to take the measurement in-situ, not move it, but there are situations where you just need too (e.g.: my struggle with reading the print on the tiny one). They come with holes in the ends for hanging or tethering, but I’ve never done either with a goni. I compared them to one I already own, and with each other, and they seem accurate.Note, the text on Amazon page is for a different item, but the photos are accurate.Edit 03/23/2025: I am a visiting therapist, traveling in my car from home-to-home. I was carrying the gonis in a plastic bag, in the 'map pocket' on my car door. Recently pulled them out to use and discovered the arms have bent slightly to conform to the map pocket. I can go a few months at a time without needing the larger ones (pedi therapist), so I'm not sure if it was the car heater over the Winter, or the natural heat of the Summer, that softened the plastic so it bent, but I don't think I can consider them reliable measuring devices any more. So, keep them away from heat sources and they should be fine. Other than the warping, I've had no trouble with them.

If you work in health care and utilize goniometers, you know that these are not a fancy item but they are extremely helpful when assessing joint range of motion.Sizes: when measuring from the axis point to the end of the arms, this three pack includes a 10", 6 1/2" & a 5" tool. The degree markings are clear and easy to read. The arms have both metric and standard measurement increments. All three of these goniometers has a hole in the end of the arm for hanging if needed. The two shorter devices are quite flexible and the 10" device is a bit more rigid, simply due to the thickness of the plastic.Again, nothing fancy but they work great!
