I'm cleaning out my computer office and found this that I was keeping as a backup after I bought a much more expensive unit. This one works perfectly. I haven't tried it with window 11, but I have it installed on my windows 10 laptop with no problem. It has the original manual and install disc. It powers up by a USB cable (included). I've used it with both slides and 35mm negatives. This is a good way to digitize your slide or film library. If interested please respond to this posting and I'll get you contact information. I'm near 120th and Sheridan. Cash and local only. Thanks for looking.
