Angli Ear, were of great help, firstly going to them with a bad tinnitus problem, not knowing, that really I had a hearing problem. So with there help and support I now hear low treble noise like never before. If I said I now hear in colour, instead of grey, that may help you understand the difference!!!. All the staff go out of there way to make you feel at easy. What was of great help was the 30day free trial, the product kind of sells it self once its fitted and adjusted to meet your needs. Do I recommend them, yes I do.
