3Mlittman cardiology IV Stethoscope
This product is for my daughter so I'm really not sure about the working results. The timeliness and the engraving were well done. My primary concern is that it was listed on your site at two advertised prices both lower than what I was charged. I asked about this when I placed my order but heard nothing. So I'm asking again. I hope to get an answer this time as the difference was quite a bit. Thank you

engraved stethoscope
I was very impressed with the prompt delivery. However, I had the stethoscope engraved and it is very tiny. I feel like that was not clear when I added the engraving to my order.

3M Littman Cardiology IV Gift
Went extremely well - and quick as daughter in NYC area. She loved it, and all were happy. Note: I could do without being on the junk email list as this was a one-time purchase , and not being a vet myself, I have no need for these things myself.
