Finally opened my hydrology9 NX last night to tinker around. The first thing I noticed while reading the instructions is that my flower atomizer is not the same as what was illustrated or instructed in the guide. Instead of a nice magnetic top, it had something of a screw-on top which I didn't like. I don't know if I got some old stock or a redesigned flower atomizer but I wasn't impressed. Also, my hydrology9 does not change colors when adjusting the temperature so it's always a guessing game. I feel like the product has so much potential, but I also feel like I got some thrown-together device with mismatching attachments.
