Easy to use and performs well - trouble is it dies too readily. We are (or were) on our 2nd BT Response 75: our first just saw out the warranty, dying after 13 months. We had liked it so much we bought another, but this has now also died, albeit after 2 years. Is it me? Do I expect too much? For your info, 'we' are a UK couple in our 60s, so no kids at home, and only normal domestic useage. I agree with Kotovasii re PP3 batteries - they are very expensive and (possibly) unnecessary - but their cost pales into the proverbial insignificance when compared to repeated renewals of the entire unit.
