Wont waste too much time on this. It aint worth it !1. The scanner is darn slow.2. Go for scanning dark slides and you are in for a real shock. No amount of 'Gamma Correction' or 'Hue/Brightness/Contrast Setting' would set it right.3. WORST EVER Technical Support. The only free support is email based. Whats worse is that the site doesn't have this 4900 model mentioned in some of its driver updates section. Free Technical support is only for Installation - that too only for the first 90 days. All others s 15$ incidental !4. Talk about using the good scanning software like VueScan or SilverFast and u'r in for another surprise ! None support this scanner.I have been sitting before this piece non-stop for the past 3 days. Just cant figure out how can anything be sooo horrible. This piece goes back and I can finally have some peace of mind !
