Anyone have any experience with one? I'm looking for an under-saddle pickup for my Washburn and this one seems to be the cheapest while getting good reviews. It's about $60 online. I kind of dig it because it's passive and will require very little mods to my guitar. I don't really feel like removing the strings every time I need to change a battery or cutting a huge hole in the guitar for a battery compartment.

Give me your thoughts on this.
