The SMOK Solus 2 strips things back to the basics, which is the appeal. It's a slim, pocketable device with a 700 mAh battery and no buttons to deal with, since it fires on the draw. The 2.5 mL pod refills from the device and uses an integrated 0.9 ohm coil, a resistance that sits comfortably between a tight mouth-to-lung draw and a slightly looser one, so it handles salt nicotine or lighter freebase without much fuss. Output tops out around 17 watts, which is modest, but that's in keeping with what this device is for: an easy, low-maintenance vape rather than clouds and power. The zinc-alloy body keeps it sturdy despite the size. It's a good first refillable, or a simple backup, for anyone who doesn't want settings to think about.
