Great bulk deal. The only disappointment is the packaging as the strings get often stuck within the tube they are fit into. That's not very handy, it can be improved. Aside from that, I'm very satisfied with the product.
I was using the 10-46 gauge for years. I decided to try the 09-42 gauge and I found myself really comfortable, considering the playability and the easiness of all kind of bends. Of course as a faithful user of the 10-46 25 sets' box I immediately bought the 09-42 one. Really comfortable and practical! 5 stars really!
This strings are in my opinion the best for regular gigging and the bulk box saves a lot of money. No more running out of a set of new strings. Less packaging to recycle too which is good. I just love the feel and tone of Daddario strings. If you play for an hour a day or more then bulk buying is the way to go.
