My mum has a very quiet voice due to Parkinson’s. We bought the voice amplifier from Parkinson’s UK but it’s too fiddly for her. You have to hold down a teeny button for 3 seconds to turn it on for starters! Such a poor design. It has lots of different switches which are confusing. We just need a simple on/off switch and a volume really and something which doesn’t give too much screeching feedback. There are hundreds on Amazon but hard to know where to start with all the conflicting reviews so a personal recommendation would be great. Thanks
