It is a fine hi res, sensitive guidecam and good value - I use mine with a WO66SD and Guidemaster but have also used it with PHD again guidestar options all over the fov never have to go over 2s but sometimes I do to compensate for seeing effects. There are plug-ins for other programs too - eg AA. My feedback can be found here:

Most recently this has been rebadged by Orion I believe, OpticStar also produce a similar unit though it is configured to stream video (like a webcam) rather than individual frames an cannot go more than 2s in that mode but it does open up the possibility of using other guideprogs such as Metaguide...
