    Reliable quality and service

    This arrived just one day after I ordered it! For regional Australia, that’s so quick. And the stethoscope was the great quality expected.

    Speedy Delivery!

    I ordered at 10pm one evening, and it was waiting for me when I came home from work the next day!!! The Cardiology IV is amazing. There is a reason to pay the extra money - Such a huge difference to my Classic III. Love it.

    retrieve evidence of previous purchase

    very good, replacing a stethoscope and an ophthalmoscope, among other items which lost when my instrument bag was misplaced or stolen from an airport baggage checkin. Unfortunately you were not able to provide evidence of my previous purchases of this equipment from you which I need to make an insurance claim, as I was advised that you are not able to search your sales records by purchaser name, and only by detailed product information which I have not yet been able to locate. I was advised that this deficiency is to be recrtified.
