Slide show options include a smattering of transition effects, slide interval (from 5 seconds to 3 minutes), and the capability to add a small, onscreen clock. You can view the calendar side by side with your photos or a clock. Text isn't very pleasing to look at, but if you're using this on your office desk, it's a nice option. The frame's system menu features adjustments for brightness, contrast, and saturation, as well as timed Auto Power preferences.
To say I had low expectations from a sub-$40 display would be an understatement; for that price, if you can recognize people and locations in the photos, you're doing pretty well. Photos look OK, if you're not too picky. However, if you are, you'll notice that blacks and highlights are clipped, there's little in the way of midtones, and colors are oversaturated and occasionally off. Because it's low resolution for the size (480x234-pixels) you'll also see a lot of jaggies along diagonals. On the other hand, it performs surprisingly well. Transitions are, for the most part, smooth and transferring photos to internal memory is reasonably fast. (But again, I recommend viewing from a memory card or USB drive for the best picture and performance.) The display gets fairly bright, too.
Hannspree includes a one-year warranty for parts and labor--far more than the 90 days most manufacturers offer. The company also offers toll-free phone and e-mail support weekdays from 7 a.m. to 6 p.m. PT.
The Hannspree SD7021 7-inch digital photo frame is a good option for anyone just looking for a cheap way to quickly and easily display digital photos without a computer. It's not perfect and doesn't do much beyond show photos, but it's definitely better than its budget price would indicate.
