For the price, this is a no-brainer.

Here's what the device is not:
1) It is not an HD Device. No 1080p video here
2) It does not support every file format under the sun
3) It is not a couple hundred dollars

Here is what the device is:
1) This device plays DVD-quality video
2) It plays the most common formats for downloaded TV shows and DVD-Rips, namely Divx & Xvid. I have also found that occasionally it will play an MP4 file, but it makes no such claims.
3) It is very inexpensive

Here's who should not buy the device:
1) People with collections comprising largely of BluRay rips
2) People who need network-support to retrieve from a server
3) People who want to spend a lot of money

Here's who should (at least consider to) buy his device:
1) People with DVD-Rips or downloaded TV shows on their harddrive that they would like to play on their TV (like me!)
2) People who sometimes connect their laptop to their TV to watch video but dislike the lack of a remote control (like me!)
3) People that would like to buy an expensive Media Player but don't have $100-200 (like me!)

Let's face it, there are a lot of devices that do this, to varying degrees of success. When you make a purchase like this, there are a few things to consider:
1) Will it play the videos I have?
2) Does the navigation suck? (Some devices have issues with forced previews that make loading video painfully slow)
3) Will it break my budget?

For me, this device plays everything I have to watch. The navigation is quite nice, it has a preview of video, but on a slight pause so that it doesn't scroll file to file slowly & I could afford it. A couple days after getting it, I recommended it personally to about a dozen people including co-workers without reservation. For what it is, it works exceptionally well. I see no discernible difference between this device plugged in via composite and my netbook playing the exact same video files on my 32" 720p TV. I am not connected to it in any way except as a very happy owner of one. Highly Recommend.

Got this beautiful little box and it works great,Compare too some of the high end models this little box does it all for about QUARTER THE PRICE over the other boxes out there.I play alot of dvdrip.avi files and it has not failed yet !!!!good buy under $40

This device is worth buying if you have a lot of videos or music on your usb drive or external hard drive. I have been using it for more than a month, it has exceeded expectations in most cases.

PROS: Works with external hard drives, Flash Drives, Memory Cards, has a remote control, it allows continous playback from the last spot you stopped.

CONS: Remote buttons sometimes get stuck. You cannot read the complete file names, if they exceed more than 20 characters, you have to wait till a rollover text comes to display the whole file name. It makes it difficult when you have have 100s of files in your drive.

I have this NBOX TV Player for about 5 months, it works very well. It's not the best flash media player, but it's a lot cheaper than other brands which are all around $100-$200. I believe this one has the best value for that price.

NBOX is very easy to use, just put video files into SD card, USB flash drive or USB external hard drive. I personally used a 16GB SD card to carry my kid's cartoon, and use a 750GB Seagate External HDD to carry the movie or tv series for my wife and myself. The remote is very easy to use, and my little 6 years girl could use it by herself, no more bothering me.

Pros:
1. Support a lot of file formats: AVI, DIVX, XVID, RM, RMVB, MPEG, it even supports subtitles
2. We like that remote controller, it's one of the biggest advantage than hooking up my laptop/pc to the TV.
3. Auto Resume from last stop point. When I stopped watching a movie in the middle, I just hit power button on the remote to turn NBOX off. Later, when I power on NBOX, it would automatically resume the movie from the last stop point.
4. Continuous Play on Multiple Files. Sometime I watch TV series with 20 episodes, NBOX could smoothly play one episode then play the next one. I guess it uses the file name to sort the order.
5. With the component cable (included), I can get 720p HD output quality on my LCD HDTV from NBOX.
6. Price. It has the best price, almost the same as a regular DVD player. I can't find a cheaper one which could do so many good things.

Cons:
1. It doesn't support MKV and MP4, which is a pity. But 95% of my files are in other formats, and I don't want to pay $100 to buy other media player for just 5% usage.
2. The red power light is always on as it's designed for indicating the power cord connection to the wall jack. I wish it would be off if I turned off NBOX.

Overall, I am very satisfied with NBOX. It has very good value for such low price, and it's very easy to use. I am hoping to see new models with advanced chipset which could support more formats in such low price in future.
