Review on NEUTRIK NDM Dummy Plug for Male XLR Chassis Connector (10-Pack) by David Edwards

This is a near perfect solution to protect charging port for OneWheel+/+XR. It doesn't form a perfect seal for the entire cavity, but it fits nicely into the charging port. This will prevent almost anything that can get in there, be it dirt or water. However, they cannot harm the environment of the cavity. This means it should be fine for any debris you come across, but you should be more careful with things like wet or snow. Sometimes condensation can cause problems that disconnect does not occur when moisture builds up around the seal that normally evaporates or does not reach the inside of the seal(s). There probably won't be any problems, but the connector isn't tight, just enough.
