Pros: Very small and light.
Plenty of battery life for even a long meeting or presentation.
Flexible inputs/sources (built-in memory, Micro SD, USB, HDMI, WiFi, Bluetooth)
Familiar Android user interface
You can actually charge other devices from this device (although not while projecting, even when it's plugged in).
Tripod mount is very handy, but sadly necessary due to the lack of any image correction or zoom capability.
Cons: I am an Android novice, however I would think that the mobile hot spot feature would be relatively easy to enable, yet after quite some time poking around, reading the manual, and even searching online, I was unable to figure out how to turn it on.
A zoom adjustment knob would be very helpful for the projector. As it is now, you must move the projector to the correct distance from the wall to get the size you want. For example, placing the projector 8 feet from the wall, yielded a 60" diagonal image of the home screen. To reach the quite fuzzy maximum specified image size of 120", which will be viewable only in total darkness, the projector had to be about 16 feet from the wall.
This is not a bright projector. If the there is ambient light and your screen is bigger than a couple feet, it's going to be hard to see. With the lights dimmed, it's passable, but only if the screen size is kept pretty small.
While the projector is on, a rather noticeable fan is also on. This would definitely get annoying during a meeting.
The built in speaker is quite poor. I am not sure why they even bothered. There is an earphone jack though.
The ability to charge or operate the device from a USB power source seems like a no brainer given its portable design, yet it missing for some reason, forcing you to carry around a wall wart power pack that is half as big as the projector itself if you plan to exceed the battery life or need to charge.
Another sorely lacking accessory is a carrying pouch or even a lens cover or shutter.
Strangely, there is a second power button centered on the left side of the device, just begging to be pressed every time you try to move the device. This could have been much more conveniently placed on the back with the power adapter plug.
Other Thoughts: I have mixed feelings about this device.
In all fairness, it performs decently well for its size and the fact that it is battery powered. It could be a little brighter, and they could have done something to reduce the fan noise, but for the most part, it would be a handy little device for a traveling salesman or teacher to present from their laptop or phone. While the Android touchscreen interface is cool, I don't see anyone trying to use it during a presentation. Perhaps to start a movie or slideshow it would be fine, but beyond that, you would make everyone in the room nauseous with all of the screen wobble as you worked the controls.
But then you have to consider the price and the alternatives. When comparing to other portable projectors, this device falls right at the average price of everything here at Newegg, but has the lowest brightness and the lowest resolution of the bunch, which puts it significantly behind the pack for the 2 most critical specs to consider when choosing a projector. On the plus side, this is the only one with an Android interface, but it's an awfully old version, and if you can hook an HDMI cable from your Android phone to any projector, is it worth the added price to have it built in?
Obviously, if you're not looking for a tiny travel projector, you shouldn't be looking at this device at all, as there are much better full-size devices for the same money.
This review is from: Seagate Seven mm 500GB USB 3.0 Portable External Hard Drive STDZ500400 Silver
Pros: Reasonably fast. Sleek look. Robust backup utility.
Cons: Comparing this $100 hard drive to the $63 Seagate Backup Plus Slim 500GB USB 3.0 Portable Hard Drive STCD500102 Black, which I reviewed almost 2 years ago, the results are very unfavorable for the Seven.
Both drives ship with a paltry 18" USB 3.0 cable, although the Seven's cable is braided.
Both drives are very small, although, while the seven is thinner, it is also bigger than the Slim:
Height 4.836" (122.84mm) 4.476" (113.70mm)
Width 3.241" (82.33mm) 2.989" (75.92mm)
Depth 0.275" (6.99mm) 0.381" (9.66mm)
The performance of the Seven also falls considerably short of the Slim, as measured by every Crystal Disk Mark benchmark:

Other Thoughts: As stated in my previous review:
The included software (Seagate Dashboard) is quite simple to use, and is a pretty robust backup utility. You can specify what kinds of files to backup (all files, personal, documents, etc...) or manually select individual files. You then decide whether it will be a 1 time backup, a periodic (every hour, day, week, or month) or a "continuous" backup where it tracks when files are modified and performs real-time backups. Backed up data can then be directed to this drive or to a cloud storage account. Included with this purchase is a 1 year cloud storage subscription with 4 GB of storage.
Once you log into Facebook or Flickr from within the dashboard, you can easily upload or download content from your account. You can also log into YouTube from the dashboard and upload movies, however you can't download them.
In summary, unless you really like the look of the new drive, it's not worth the performance hit and the significantly higher price tag.
This review is from: SteelSeries Siberia v3 Circumaural Headset
Pros: Very comfortable. You can actually forget that you are wearing them.
Above average sound.
Good length cord to connect to a portable device that is in your pocket, and comes with a nice long cord which breaks out the 4 pin 1/8" plug to a separate 1/8" headphone and mic connector for your PC.
Retractable and adjustable mic is a great idea.
Mic mute switch is a nice idea but see cons.
Cons: The headphones seal so tightly, I can actually feel the air pressure on my ear drums when I put them on. This could be very dangerous if someone came up behind you and pushed them towards your head, or pulled them away and let go.
The Mic is not very sensitive. You must extend it fully, and bend it right in front of your mouth for it to be usable, and even then, you must speak louder than your normal talking voice.
There is no mute or volume control.
While there is a mic mute switch on the headphones, a lot of noise is generated in your left ear as you fumble around to find a move the switch. It really needed to be on the cord.
The tone is a bit heavy in the bass range. The USB version allegedly comes with a tone-control application (SteelSeries Engine 3), but this one does not. You might be able to download a third party tone-control application off the internet, but it would have been nice if one had been provided for this price.
Other Thoughts: I have mixed feelings about these headphones.
If you are looking for a headset either for talking or for listening to music on your mobile device, these might be a little over the top just due to their size (these are pretty big headphones). My guess is that they will also run your battery down pretty quickly.
If you are looking for something to use with Skype, etc...,, or in-game voice chat services, you might be disappointed with the mic sensitivity and the fact that there is no volume control on the headphones.
If you are just looking for a good quality, comfortable, pair of headphones to listen to music, these will fit the bill, however for this purpose, there are far less expensive options that sound just as good, or much better quality headphones for about the same price.
Overall, I would say that while these are not bad headphones, for this price, there are much better alternatives out there.
