I bought one of your stethescops (SP?)and with engraving. I was told your $50.00 model was OK. wrong! I got the product and I felt it was inferior, plus no engraving. I spoke with your CSR and I was given several acceptable options. It's a gift and do not have time for return of product. So, I will let the gift receiver handle return/upgrades and engraving. I was disappointed in the quality of the product and no engraving---yet I was charged.
