Just received my X4, and it seems to work really well. One concern is where the TEC wiring exits out the rear of the heat sink. The exit hole seem pretty small, and I'm not sure just how sharp the edges are? I worry that over time movement of the sensor will eventually cause the wire inlsulation to fray ,causnig a short. Anyone see any issue with a small dap of hotmelt plastic at the exit hole to prevent wire movement / chaffing. Would a 3 watt laser remelt that glue?
