I finally picked up a DNA200 and have been playing with it. It has some nice features, but my go to chip remains the sx350j. To really get the DNA200 to work well, one has to use escribe to setup a preset (e.g., the default preheat of 200W is way too much for my RTAs and gives a nasty initial hit, so I had to set the preheat lower). Escribe works, but it's painfully slow on updating and is the only way to adjust certain things, such as the preheat settings. With the SX350j, anything I need to quickly change can be done with the menu settings or up/down button. Thus, the SXM I find is much more on the go friendly than the DNA200 (which really needs to be hooked up to a PC to access functionality that should have been available from an on-chip menu system).
Also, now that I'm used to the Joules counter, it's something I really miss on the DNA200. For example, my battery bar is claiming it's full on the SXM, but I've already used 5.5kJ, so I know I've used 20% of my battery. Unlike a battery bar, which is just based off the battery voltage, a Joules counter gives me a much more accurate measure of my usage.
Well crap I wasn't aware I wouldn't be able to adjust the preheat on the device without using Escribe... That's just dumb IMO. So if I go to a local B&M and want to try another atty or put someone else's build on, I'd need to connect to a PC if I needed or wanted to change preheat. Yea that's dumb dumb dumb. Maybe they'll add it in firmware at some point. I should receive my DNA200 powered device tomorrow to compare to the SXmini M. Just praying it works out of the box and continues to work. I was very hesitant in making the DNA200 purchase with all the failures reported across the board from components falling off to burnt chips or just dying after a few days/weeks of use.
