Marthese M. (California, United States)
Easy to use and helpful for my condition

My OB wanted me to get a doppler to monitor baby's heartrate for a certain condition so I ultimately decided on this one for it's reputation and cost. I wasn't disappointed. It's easy to use and worth the money.

Tami W. (Oregon, United States)
Great doppler

By far the best doppler I've purchased.

Christiane M. (New York, United States)
New doppler

I needed a second doppler for my practice, one that was waterproof. I've recently started to use it for home visits and am very happy with its features. Easy to use, the readout is helpful and I love that it is waterproof!

I enjoyed the ease of ordering and the prompt response to my questions from MRI Medical.

I look forward to working with them again for any future practice needs.
