I've been browsing the above this evening. I bought the minimum amount of units possible (60 for £6.95) and almost spent the lot on just a few military records.
I have to say I am quite disappointed with what I have for my money. The only records really of any use to me are from the Soldiers Died in the Great War database, these were 10 units per record. Frankly, they tell me nothing more than I can find on the Commonwealth War Graves Commission site and thats free! The only additional info I can see is 'Enlisted' but even this only gives a place and not a date.
The only piece of useful info that I have been unable to find elsewhere (but have never looked for) is an overseas death reference and that was for a soldier who was killed in action.
Another area which disappointed me was the lack of information about the records. Had I have been able to read a decent description of what the records contained (like on Ancestry), I probably wouldn't have bought the units. If the descriptions are available then they are not obviously visible.
A real disappointment!
