I purchased the SmartU Bluetoooth Hearing Aids for Seniors. I am actually in Day 4 of the learning process. So far my experience with them has been great. They were easy to connect to my WIFI. It was easy to download the app to control the hearing aids. I love how easy they are to charge and keep protected when I am not wearing them.
