It is a well perceived notion that all things technical has a shelf life - limited lifespan and it is difficult to put a date on anything as there are so many variables that affects the outcome of that particular technology. I view it the same with hearing aids and as CI as well. External parts of the CI is easily fixed and the company always kept on top in regards technological advances. The internal part - well...that's different, but it is good to know that the internal part is backward compatible and is made of materials that will last the person's lifetime. Yes there is a small percentage where this does not happen, like I said - variables influences the outcome. I would say the same if one is having an operation for something that will help enhance the quality of life. The surgeon is bound by moral ethics that they have to quote pros and cons, the percentages of success and failure.
It does sadden me that when people complain that things break that easily - one has to remember that we do pay the price for convenience - products that are churned out at quantity and low prices that such equipment now have a short shelf life compared to those in the past where quality was paramount and it lasted for ages.
Nor that they see the bigger picture that short term issues are only what they are and can be ironed out - for example - Skoda cars, at first they were laughed at and it had a poor work history, but they worked on it and ironed out the problems and now they are great and the cars they make are of better quality than the earlier models. We should be more aware that technological advances are continuous - seeking improvements on the old and it invariably invites errors/mistakes and the only way to learn is to learn from mistakes ONCE and move on.
So I say - take it with a pinch of salt and take necessary care and precautions, then your piece of technology should last you a good time until the upgrade comes up. And I am pleased to say that the replacement processor has been trouble free for the past year and half.
I have been using the compilot mainly for listening to music periodically and in sneaky situations where listening to music is banned i.e. libraries (ssshh!), the brilliant thing about compilot is that its absolutely quiet and streams wirelessly to the CI and HA! Bliss...
And as for the aquacase - I have used it in the colour run obstacle in Bath in July. It's great fun knowing that you no longer need to worry about getting the CI or the hearing aid getting contaminated with foreign objects - flour, water or rain! I completed the course in high spirits and hearing the good music, laughter, screams and running feet - it brings me a smile whenever I think about this event.
