Review on ⚖️ Hanchen Digital PD Meter with Memory Function - Pupil Distance Meter PD Ruler Pupilometer | CE Certified by Ryan Marx

Revainrating 5 out of 5

Good product, best electronic product

Good product. Worked exactly as advertised. Easy to use, but a second person will likely be needed. The measurement only takes a few minutes. Seems very accurate. The battery is not included, so you need to purchase it separately.

Pros
  • Easy to read control panel
Cons
  • Nothing
