Review on 🔧 Magnetic V Groove Backlight Protractor Inclinometer: Ideal for Precise Angle Measurement & Alignment by David Lesperance

A little clunky but works. I would have liked a little more precision and precision, but I need more than the standard usage of this product. I use it to read the altitude on my telescope. With a wide field eyepiece this is sufficient. I bought it to replace the non-illuminated model, but the blue backlight is too bright for good night vision. Again, these are ailments very specific to my particular use. The backlight brightness is probably good for daytime use and other applications.
