I have at least one of almost every kind of sensor, and a GW1000 and GW1100, so if there's something you'd like to know about their behaviour, let me know. (I have WH31, WH31P, WH32E, WH32B, WH34, WN35, WH40, WH41, WH45, WH51, WH55, WH65, WH68 devices, and several of all the multi-channel ones except for the WN35 leaf sensor.)
