Example Input: This is a well-designed USB 3.0 hub, which lets you add additional USB devices to a single USB port on your computer. The hub has its own power switch and it can provide USB 3.0 speed if both your device plugged into it and the original USB port that the hub is plugged into support that standard. This item is relatively small and lightweight and it seems to work fine with any operating system and any USB peripherals. I would just be cautious about connecting multiple devices when using it with a USB external hard drive - this is an issue with any USB hub, since the power current has to be split among the ports when multiple devices are plugged in. Sabrent provided this item to me at no cost for review purposes.

Example Input: Purchased this item on June 29th to use with my new MacBook Pro. It worked beautifully in the beginning, but 2 months later it's no longer working. I checked the manufacturer's website but there doesn't seem to be any kind of warranty in place for defective products.<br /><br />I'm disappointed to say the least that this cable lasted only 2 months. You get what you pay for with this product. I don't expect to buy a new adapter every 2 months so I'll be looking for HDMI to Thunderbolt adapters from other, more reputable manufacturers.<br /><br />Please, look elsewhere for a quality HDMI to Thunderbolt adapter. This one will break down on you without reason and you'll end up having to buy another one after just a couple months.
Example Output: Negative Review

Example Input: I am highly disappointed refurbished kindle. When I received it in the mail, there was no paperwork to accompany it and I had to recontact Amazon to request a return label for the old, broken kindle. I was excited to finally use the new, refurbished Kindle but quickly found that the page turning button on the right side does not work. Thankfully the one on the left does, but I was sent a faulty machine. I do not want to go through the hassle of contacting amazon again, repackage it, go to the UPS, and then wait for another machine. I understand it is refurbished but come on- the buttons don't work. What a shame.
