The second edition was good, but it was a nuisance having to set up using three discs. This version uses just one disc and is very easy to set up with clear written instructions.
The software is very easy to use and the search engine very efficient, narrowing info down to individual parish churches in different counties in England and Wales.
I thought I'd found most of the info I'd required on version 2, but I was very pleasantly surprised and am still adding data to my family tree. For the amount of info that you get it is excellent value, even if some areas aren't covered in detail. eg if you had relatives in Yorkshire, the Midlands, Suffolk, Lincolnshire and Berkshire, you'll probably find a lot of info (more details on the Federation of Family History Societies website)
Devon, Hampshire, Lancashire, Norfolk and North Wales don't have as many entries - hopefully these areas will be included on version 4!
In spite of these gaps, I would still recommend this software very highly.
