I bought this for my dad's 60th birthday and, once I'd loaded it with masses of his favourite childhood/family/holiday pictures, it proved to be a great gift. Yes, it's 100% plastic and quite lightweight but it seems robust enough and displays the photos very well. Once it's up and running, you don't know that it isn't a high-end glass model (unless you really are some sort of digital photo frame aficionado of course).
It can stand like a normal surface photo frame - with the supplied 'leg' - or hang on the wall, and it looks pretty darn good either way. It accepts SD cards, including the newer 'Ultra II' type (don't know about the HC ones). Mine didn't come with an SD card but Play sell a great selection, many for under a fiver. I suppose you could have several SD cards containing different genres of photos - holiday, family, wedding, etc - and change them depending on your mood and/or company.
The photographs can be displayed at intervals of 3 or 10 seconds and 1 or 2 hours. Or just statically. If you set it to change every hour, on the hour, you might not see the same photo for days or even weeks!!! The contrast/brightness/hue/saturation are all adjustable until you feel it's just right. Individual photos can be zoomed in on and rotated. You can select the effect with which the photos appear/change - shuttering, sliding, random, etc - and you can also set a photo as the wallpaper on startup.
All in all, a very good bit of kit for £29.99 - quite primitive as you might expect for the money, but a great original and thoughtful gift. As I've said, once it's loaded up and on the wall, you begin to see that you made a brilliant purchase and pat yourself on the back for not bothering to spend any more.
So, if you just want to see your favourite photos and you don't expect it to make you a cup of tea, you won't be disappointed.
