[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]: This was my first attempt at a diet or exercise book. I bought it in paperback for the price of only $3.99 and thought I'd give it a try. The format itself is easy to follow, though there isn't enough detail on each recipe -- if you don't know where to start, as I didn't, it's pretty difficult getting back around to it. The actual recipes themselves are not that exciting. I've made them several times since receiving it; they taste alright, but nothing too special.
[EX A]: Good Review

[EX Q]: For a good price, they are pretty darn good. I have tried many headsets, and for $40 they're definitely worth it. Nothing special, but very comfy. My old $125 logitechs were not the most comfortable, by any means, but i wanted something much better since my last pair of $70 ones broke after just over 2 years... These aren't perfect, like it says on the description, because these headphones won't work with your current cordless phone.
