It's a good one. The Zenith
tank makes it shine. But for a basic, reliable, easy to use portable device the Kroma-A box is one of my favorites.
The display stays on just right, fire button is easy to use but a raised area around it prevents pocket fire. Adjusts in 1/2 watt increments, +/- is vertical and it's grippy enough to hold with sweaty hands while sleek enough to easily slide in/out of a pocket or sack. I like the 1.6 ohm version but most dealers are stocking Innokins new 0.5 ohm Plexus coil version.
Comes with stickerrrrrrrrs.
