It seems there's so much variation trust to trust, Laraine's went to our optician as they do the tests, she did her tests and he let her try a couple of models to compare to the NHS models, the GP has referred her but because of the results of her hearing tests he thinks the private route will be the way to go. I hope you get sorted soon. I know this sounds awful but I remember when we didn't have a choice they did one type and everyone went away happy, the more choice the more problems we seem to have.
