There is no accessories forum, so I am posting this here. I like wireless, and have been using 2 systems. I use a Line 6 G30 to connect my guitar to my pedalboard. The G30 receiver is in a pedal-like form factor, so it is a fixture on my board. I also use a Rowin WS-20 system to connect my pedalboard to my amp, OR to connect my guitar to my smaller pedalboard that doesn't have the G30 receiver on it. With 2 systems, it is a little harder to diagnose, but as near as I can tell, the G30 is rock solid, and the Rowin is pretty good with only minimal drop outs (quite good for its price for sure). [BTW, my pedalboards tun on a central battery under the board, so with these dual wireless systems, y board is COMPLETELY wireless (externally - obviously, I use patch cables between pedals). The Rowin system is a pair of small dongles with rechargeable batteries onboard. Very convenient. There are a bunch new choices in the dongle form factor, so I decided to try the Donner DWS-3. I ordered from Amazon, and had a chance to try it out over the last 3 days since getting back from vacation. Donner DWS-3 report: I just dropped it off at UPS to go back to Amazon. Nuff said? Now I'll explain. First the form, then the function. Form: The swivel jack hinge on one of the units felt much looser than on the other. This isn't a problem in and of itself, but it predicts that these hinges will loosen over time (which I have found to be true of the Rowin WS-20 units as well) with no obvious way to tighten them back up. I didn't love the little cat whisker antenna either - seemed like a weak link. Finally, there is no real battery indicator. Red while charging, green when full. But nothing to let you know how much of a charge you have remaining. Function: Sound quality was excellent, as one would expect in 2018. Supports 4 channels, and it is very easy to select one and sync them up. But more importantly, I had frequent drop outs both at home and in the jam room last night. I ended up switching back to my Rowins last night, which also drop out, but actually less frequently than the Donner, at least in the environments I used them in. As soon as the Donner system is credited to my Amazon account, I will order the Boss WL-20 system, and see if it is more reliable. At that price point, it should be better, but only time will tell.
