[EX 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.
[EX A]: Good Review

[EX Q]: Excellent video quality. It is nice to be able to leave my laptop in charging dock while watching tv from bed.
[EX A]: Good Review

[EX Q]: I purchased the iriver AFT 300 to replace an older MP3 player (which no longer worked), and am very pleased with it. My previous mp3 was a Creative MuVo X5 (model E280, which works wonderfully well); after many years of hard use, it started having problems. I replaced its battery twice, both times by using replacement batteries from local stores. This new one is much nicer, however, when comparing size with my original unit. The earphones are far more comfortable as well.
[EX A]:
