I love this Dynavap adaptor kit, it fits the Wand perfectly. You push the silicone sleeve up through the bottom of the wand till its stops. You can either use the seat cup or pass-through cup depending on how you plan to heat the dynavap. If you use the seat cup you push that from the top down into the silicone sleeve till it stops. The seat cup holds the Dynavap perfectly in place with no need to hold it. 5 taps on the power button to turn the Wand on, 2 taps to put in auto mode, and just place your dynavap in the seat cup and wait for the click, does not get easier than that. No spinning, turning, dropping your dynavap, or looking for your torch.
