## Questions & Answers

**Q: Is the product worth the price? Is the measurement accurate?**
A: Yes, mine was accurate.

**Q: Is it better to choose a plastic ruler or a metal ruler? How to use it?**
A: I have bought both materials. I bought a metal ruler at first, but its edges are sharp. I almost hurted my child's face, so I changed a plastic pd ruler. It is transparent, measurement can be clearer and more accurate. It did not come with instruction, but I can easily get the manual video from Google.

**Q: How do you use this? I need to order glasses online for myself and my children and I cannot figure this out.**
A: I googled it, watched a YouTube video if I remember correctly. No instructions came with mine, so pretty annoying.
