I got this for my mum who is 70 years old. I put some hi-def home videos on it and lots of photos.
I taught her how to use it, which is not difficult at all. It provides a clear image (up to 1080p), sound is good. It shows photos nicely with controllable speed on the slide show.
Only downside is the remote control. Dark blue text on a black background makes it difficult for me to read so close to impossible for a 70 year old even with reading glasses in good light. Plus the buttons are small and it is easy to hit the wrong one.
A better remote would warrant 5 stars but even with the little remote it is worth 4 stars.
If you have a high definition TV with a HDMI port but no built in media function this is a great way to play music / Video / Photos on your TV. Don't forget to get a HDMI cable as one is not included, a cheap HMDI cable is more than sufficient as the expensive HDMI cables are a rip-off.
