Q: This product is fantastic. Great quality and easy installation with the included video. It was installed within 15 minutes on my 2012 Chevrolet HHR. I have already recommended this to friends who are looking for a replacement mirror, as well as, some extra help installing it. One suggestion before attempting this, watch a few videos online about how it looks in comparison with your existing mirror. The mirrors will be off much more than they had appeared prior to install.

A: Good Review

Q: Interesting book. A bit too much for me, though. The authors spend an excessive amount of time talking about their philosophical views.

Q: Don't waste your money on this. I purchased and returned it within 3 days. It was bulky and didn't really work well. You couldn't find a good angle for the phone so the audio kept cutting out. My son tried it. He is using his iPad without earbuds. We will buy some quality wireless headphones, he said. I'm not buying another one. This one isn't worth wasting my time. The headphones cost about $30. So even if you don't need to be out running, these won't work. Do what I did.
