## Questions & Answers

**Q: does the white/rose gold stethoscope get dirty from your skin/the environment? and if so, does it clean off easy?**
A: I have had the white/rose gold stethoscope for almost 4 years, it has great sound and is comfortable, but I will never buy a white one again because it does pick up some of the color of the scrubs I wear and ad is beginning to yellow on the neck area of the tubing.

**Q: Can the Rose Gold be cleaned with alcohol without damaging it?**
A: Yes, you can clean the rose gold with 70% isopropyl alcohol pads, and it will not damage the rose gold.  If anything tarnishes, please reach out to our customer service department as tarnishing would be covered under our Lifetime Warranty program.

**Q: I am a third year veterinary student, and this will be the first stethoscope I will buy.. I am just seeing how well it woks for veterinary students..?**
A: The MD One stethoscope is a versatile stethoscope with a great Lifetime Warranty program, so if you are experiencing any manufacturers issues, we will repair or replace the parts.  We also offer Free Parts for Life so if you need new ear tips, a diaphragm or retaining ring, please reach out to us at 818-377-5647.

**Q: Where are these made? Thanks.**
A: Thanks for your good question. Where are our products from? That is a complex question to answer because they are conceived and designed in our headquarters in Los Angeles. Sometimes the best materials, components and manufacturing can't be found in one country. That's why we scour the world for the best possible materials and components from countries such as Taiwan, Japan, Germany, etc. and the final assembly is handcrafted to meticulous standards and jewelry grade finish by our artisan craftsman (some with over 30 years of experience) in our dedicated facility in Shanghai to be sold in over 85 countries all over the world. All of this said, this is simply how we are able to deliver the best (listen to what our customers have to say - check out our excellent reviews). Thanks in advance for your business!
