ColorVision Spyder2 Express Win/Mac

I recently changed over from a PC to latest iMAC. Transferring software for this product I found a prompt for a serial number. However I had long since thrown the packaging. Reading general customer comments on the web I found a lot of negative press for Data Color help desk and complaint that customers could not get the serial number. However my experience was very good. I got a quick response, you just need to quote them the number on the USB plug. Calibration worked great!

The colorimeter itself seems fine, but the Mac OS X software for this unit is buggy and not a universal binary (which, if they were going to update it for Intel Macs, I would think they would have by now). Twice I had it crash at the end of a 10-minute calibration, before I was able to save the profile. The app would subsequently hang on opening, so that I had to completely uninstall it to get it to launch again. I returned it and will spend the bigger bucks on a Gretag-MacBeth or Xrite unit.

This made a big difference on my gateway laptop. Before, some things just didn't look right. This brought a new level of quality to my laptop monitor. I highly recommend it. It is pretty easy to use.

The product is easy to use and worked well for me, except I had to send it back because it cannot handle a dual monitor setup with 2 profiles. I confirmed this with the vendor. So, go for it, but only if you have one monitor.

I have a webcam site and I do extensive photography. I use Photoshop CS3 and have used Photoshop and Premiere since they were introduced. I thought I was good at monitor calibration with adobe gamma, nvidia calibration, etc etc.
The Spyder2express did a better job in 5 minutes than I can do in a hour (or forever). It was a huge improvement in all my color matching, print, monitor, and webcam color balancing.
I have two computers that use the same monitor. I switch back and forth with an iogear kvm. One PC has a high end graphics board, the other a cheap board for my webcam. The spyder2 calibrated both PC's to the same monitor so well that I can't tell the difference when quickly switching between computers on the display. It worked better than I had hoped. I may not need to upgrade to the spyder3 but I may do it to get control of monitor color temperature.
