Experiences with Paragard (copper IUD)?

I'm looking for a non-hormonal birth control after my unpleasant experience with Implanon. My husband and I currently use condoms and spermicide but we've grown to dislike them. 
Can anyone share their experiences using Paragard? I'm a little scared of the thought of using an IUD but I'm not seeing better options at this point beyond sterilization which isn't preferable.
