What can I say, it’s a power adapter so I don’t have to burn through batteries unnecessarily while playing at home, so I can save the batteries for when I go adapter-less at gigs.
I haven't had the chance to gig with this product yet. However, I jam a lot at home, most of the day in fact. It seems to be holding up quite well. The option of clipping on or off the electrical probes is a bonus. I don't know how many times I've packed similar products away that took up more space. I would recommend this power cord to the light traveler and buskers. Oh, and of course all my harmonica friends out there too.
