Whatever you do, don't buy Nano hearing aids. More of "if it sounds too good to be true, it probably isn't." They will send you something that does not work with a "money-back guarantee" and then god help you when you try to get your money back. Even if you get through to someone they try to upsell you on the "better model, pay nothing more" with another "money-back guarantee" which, fortunately, we did not fall for. We eventually did get our money back but we had to escalate and bug them incessantly until they finally gave us a refund.
