So far I scanned about 250 slides using the ClearClick 20 MP Converter. I have a few thousands to go.As expected the image produced by this converter is nothing to brag about. It is OK for a converter in this price range but nowhere near the image you see when you use the slides in a projector.Without any corrections in the converter's settings, the image is somewhat dark, a little too much contrast and seems to have a blue/green dominant. These can be corrected to a point using the converter's settings, or better, using your photo editing software. I did not test the software supplied with the converter. But keep in mind that even the best photo editing software would have difficulty adding image items that are missing. If the original image is out of focus or if the scanner output is blurry photo editing would not do a good job at fixing it. Also any image detail lost in a high contrast or low contrast scan does not have a good chance to be brought back. The dynamic range of the scanner is much lower than what you have on a good slide. I had several slides where skin tone suffered from ""burn out"" in places where shadows and bright light were present. The original slide does not show this ""burn out"". But this is expected from image pickup devices in this price range.So far I did not have the dust issues that other reported in their reviews. However I did have a problem with the glass where you place the pictures for scanning seemed to look dirty on the underside. When the scanner's light source was turned on the glass looked like a car windshield that was not cleaned in a year. It showed several round marks and around the edges seems to have a haze. Fortunately I was able to use my fingernails in a couple of indentations on the right and left edge of the scanner to lift the glass. The glass seems to be held in place by 2 short and narrow pieces of double sticky tape. I used the supplied cleaning cloth to clean the underside of the glass. You need to be careful that you do not start smearing the sticky glue over the glass surface. The mirror looked clean but I gave it a few quick squirts from the air spray can. Carefully place the glass back with the 2 sticky spots down and press lightly over the spots where the sticky tape is to secure the glass. Needless to say that you should do this in a dust free area. I would also avoid doing this when the humidity of the air is low.The included 8GB SD Card is OK. I don't think that many buyers would miss it since most people have these cards laying around or can get them pretty cheap.Once you accept the shortcomings, this is an OK photo, film and slide scanner.
