This thing worked fine for 3 months when you plug in earphones. Then one stopped working.
Bad review

I used to give this product a good rating since it did the job well. It was then discontinued, so my husband and I have become &#34;users,&#34; meaning we tried them out for about 1 month. Now they are all gone or really expensive, and we've found nothing that's as effective. My husband has tried other brands in his quest to find something even remotely comparable that actually works but none of theirs do. They're expensive too.
Bad review

This is an ok book. Nothing spectacular like other reviewers said.
