So we're not looking to buy at the moment before you jump all over me saying DON'T, FOR THE LOVE OF COD, DON'T DO IT
But
There is a thread going elsewhere where someone's considering it and a few people have said it absolutely worked well for them.
So, because I don't really know a great deal about them, I'm asking you folks here for your experiences/those of friends, family, etc.
Probably when we do buy, my OH absolutely wouldn't want to go for it, he's very risk adverse (as am I, but a teeny bit less so). But I'd like to hear all the reasons why it would be the worst idea in the world (or not) please!
