Loving every bit of it. It sounds amazing. I installed it for myself but if you are to drill a hole in your guitar, I would suggest you take it to a good luthier. If you are into fingerstyles, I would highly recommend this. I'm not sure how long will my 9v battery inside last but changing it might be a little uneasy. Every time you wanna change it, you have to losen your strings and fix it. Apart from that, it's way too cool.Good delivery service as well by Bajaao.
