I have had my G50 for almost a month. About a week ago I noticed it was going through batteries like crazy! May a fresh set of Alkalines might last an hour and a half and then it was cutting out on me and sometimes when I was right next to the unit. I switched to RF1 and SSDD. I have contacted the retailer and they are sending me a replacement but where I am concerned is... Is this ongoing? I cannot deal with this kind of uncertainty during a live performance.
