Review on 📏 Huanyu Digital Pupilometer: CE Approved PD Meter & Pupil Distance Measuring Tool (LY-9C) by Charles Salgado

This instrument looks very similar to the Essilor instrument but differs in quality. You have to deal with that all the time. I bought two at once - one didn't come working and was sent back for replacement. Received the replacement quickly. Both worked flawlessly for about two weeks, after which one of the local/remote controls started to get stuck in one position and became very difficult to change settings. Conclusion - I have one of the three that still works. Would not recommend buying. The product is not professional quality!
