Who we are
A veteran friend of mine, who has significant hearing loss in both ears due to service-related injuries, has faced challenges with traditional "micro" hearing aids, including frequent ear infections, technical issues, and high costs.
He previously relied on an old Radio Shack Personal Hearing Device, which met his needs, but these devices were prone to breaking and finding a reliable, working unit online was increasingly difficult.
In response, DotRat developed the first DMF1 for him.
He has been using it for nearly a year without any issues or problems.
