Question: amazon
Document: While the internal hard drive was not included, I was able to pick up a cheap 3TB Barracuda drive from Amazon which works great.
Several sets of batteries later, we decided that the HD720 had some serious issues and back to Amazon it went.The HD720 certainly has potential -- it's just not there yet.
I got this with Birthday Money from my parents and in-laws. I selected this one partly due to the good Amazon reviews, and those reviews were very correct. It was very easy to set this up. I used HDMI, because my TV has it, but it has RCA connections as well. The picture is great, and plays files without any problems.
I bought one from my friend who bought from Amazon . He told me how great it is . Since he is the one back up all the movies for me , why  not ?The player was good. The issue I had was a codec issue. I have mkv files it could not play. The player looked nice, had a decent remote and great video playback.
My review is based on the comparison of how these two media players stack up against one another. I purchased the KDLINKS HD720 from amazon and the MICCA EP950 was a device I had the chance to tinker with while I decided which route to go.First of all these two media players are much alike and offer a lot of the same features.
I should note that this firmware at the time of my purchase is at 1.1, which tells me this can only get better. Their website has a feedback and suggestion box which I highly advise sending suggestions for future firmware updates. I've already recommended this player to family and must say currently is the only player worth purchasing on amazon.
I have other my other video palyer systems such as the Roku 3 and and Amazon fire. All of them these popular devices had many issues when it comes to playing my collection of videos. Frequently when I could get the video working with these other players the sound did not work at all.The systems was easty to install following the instructions and all of the key cables were provided. Very nice installation.
After several firmware upgrades, two of my WD TV streamers are now paper weight. I had enough, so went up to Amazon and started looking. Then I found this media player. I ordered it after reading the reviews and have not been disappointed.Out of the box, the player looked like it meant business. Solid piece of hardware, with all the output ports you want.
I have purchased hundreds of items from Amazon and its seldom that I write a review. I've been looking for this type of product for years. I even built a PC to accomplish the same task, but sometimes a PC sitting next to a TV is an overkill. This item works as described. Install was easy. I was able to add a 4TB hard drive and it recognized it without me having to reformat.
When I bought my first one of these it failed after 2 days and I was planing a trip across the US in my motor home so I wanted a media unit to us to watch my media. I contacted Amazon and ask to have it replaced. They sent it and in the meantime the company was in contact with me and pushed the process. I got the new unit and it went over some of the roughest roads in the States and functioned flawlessly.
Answer: Is a website from which you can order this product. Also, it is a river. However, "amazon" isn't a question.
