I recently had Mirena in for 6 months. I found the peace of mind, and ease of use was brilliant as it's literally set and forget. Unfortunately I got periods that lasted for two weeks, for the whole time I had it, and that's why I got it removed. DH did also feel the string which he found a bit off putting. Having said that, my friend got Mirena at the same time, and she has had no probs at all. It's been brilliant for her. I say it's definitely worth trying, because if it works out well, it's the best contraception ever.
