Got this because of the good reviews for displaying images. The final result was indeed good but required some fiddling.
It took a second put my SD card in the slot to display some (not all) images. To display them all at my satisfaction I needed to understand the frame requirements:
Frame Ratio: 16:9
Perhaps pictures displayed on HDTV is the future as this ratio is normally found in widescreen TV, HDTV, DVD, etc. My point and shoot can set to shoot at 16:9 but my canon DSLR still shoots at the classic film ratio of 3:2. Because of this, my pics all have black bars on the left and right side of the frame. You can either change the display mode from auto fit to pan scan or you manually crop them yourself.
True resolution is 480x270 which is in 16:9 ratio. The manual states a funny resolution of 480x234 but setting my images at this resolution I ended up with black bars on top and the bottom.
Note the frame will not display images larger than 4000 pixels wide. To display you reduce the size.
Images do not shuffle and the transitions or slide effects do shuffle but cannot be adjusted.
The surrounding is clear plastic. Which is lighter and safer than glass. The corners are rounded too.
There is a clear blue dot at the bottom centre of the frame. This is perhaps for the optional remote control. But why not black to match the frame color? A black marker solved that problem.
I think these quirks reduced it to 1 star. At 4 stars its still worth the £17.99
