    Have not yet tested the new batteries, but your service and efficiency is great. Received the batteries in just a couple of days as I have with other products ordered.

    Just trying out this new type of 312; will have to compare battery lifetimes; that will take a while.

  3. *Cost/Quality/Service* 5 Star Review

    Posted by on 20th Mar 2018

    All three...cost, quality, and service, I rate "the best"! Even my own Audiologist has told me to continue ordering from you...can't get any better than that. :)
