I've used the 2018 M and the nonavong, and the nonavong is the best dynavap option imo. Titanium bowl means faster heat up and cool down. Wooden stem means cooler stem when you're heating your herb. Wooden look means it no longer looks like a crack pipe. 14mm male connection is just gravy on top. Versatile and deluxe, the nonavong is the dynavap to get.
