Ionic bands are radioactive. Research on Google  please. Made my middle finger swell and hurt and I didn't notice any benefits when wearing.

Before buying this product, do know it only works on active 3D monitors and may require some vesa 3-pin port or DLP monitor. Research before spending a huge amount of cash.

What you will be unable to know when purchasing this processor, is that Intel has purposefully disabled several functions that make it incompatible with many types of advanced software.  To not make any mention of these disabilities on the box or the descriptions amounts to false advertising and bait and switch.  When you run e.g. GPU software, and receive a message that your CPU is not compatible, and you are forced to go out and buy another CPU, please make sure it is AMD, and not Intel.  It is obvious Intel has done this to stop this processor from competing with others.  Companies that practice this kind of deceit should not be rewarded.  I have just discovered this fact, and my CPU is just 4 months old.

make sure you have a place in your car for it before you buy this.

I first tried a compatible brand, but it was not worth the savings.  Had to return it and lost some valuable time

Before you buy this, do realize that it has a serious read degredation problem along with many other Samsung SSDs using the same NAND.

I can see class action suits lining up and going around the corner.

poorly written product description which fails to fully disclose all the additional equipment, software and on going services requred to make the product of use as implied.  Almost a bait and switch.  Just be sure you realize the camera itself has rigid limitations and applications, then if you still like it, go for it.

After having already received this product, I discovered the exact same device under a different name for half the price. Shame on me for not researching better. Nice product, but you can get it for $15 bucks here:  http://www.amazon.com/gp/product/B00MYYCGKW/ref=ask_ql_qh_dp_hza
 for half the price. If the link doesn't work, type in VicTsing wireless speaker and save yourself some money.

Product works fine. However, it may be wise to show the exact product you are buying,  not the upgraded version. Deceit is not honest business is it.

Verify your wiring/fuses can support the added wattage before purchasing to avoid a mistake and wasting your time and money.

'Buyer Beware' is an old adage that I should have paid attention. I have a Mac G4, when I tried to install Leopard on my computer it told me I needed a G5. When I talked with a computer expert, he informed me it was almost cheaper to buy a G5 than try to upgrade my G4. I had already opened and intended to use Version 10.5.4. which allows me only a partial refund. I wish someplace it would have stated 'this system needs G5 or better'. That would have saved me lots of grief.

Actually, I was doing some research on this purchase - but changed my mind.  I did not purchase this item.

Do your homework before buying this, apparently a lot of garage door manufacturers make it to where this device is not compatible with opening and closing your door.

It is my fault, not Amazon's. I should have done more thorough research before the purchase. It was disappointing to find out that, for the most part, only items ordered from Amazon will work.

I didn't know you could only use the apps already downloaded by the manufacturer. Make sure you do your research prior to purchasing.

very good book, but you could learn the same stuff at[...] . I think you should give a look at the site before you buy this book.
