I am looking at either the ipv mini or the sigelei mini 30 watt, and would like to hear input from people who have experience with both devices. I am looking for a replacement for my smok xpro M50. I liked my m50, but it has proven not to be not very durable. The fire button keeps falling out (and mine didn't have the spare button in the box for some reason) the board will sometimes shift a bit in the case on me, resulting in a short that will either cause it to fire the atty continuously or not at all. When it does this I have to completly dismantle it, and reassemble to get it to work properly again. So I'm not happy with it at all really, and it has way more power than I'll ever need. I do like that it has an 18650 batt, on board charging with the USB port and its overall size. As I said, I really don't need a lot of power. My favorite atty is a Kayfun 3.1, and I use a single coil of either 29 gauge kanthanal or 30 guage kanthanal wire between 1.4 to 1.9 Ohms, and I usually vape at between 9-12 watts. I know from experience that I do not want or need something with a ton of power or the ability to fire sub ohm coils. Currently the two devices I'm looking at seem to fit the bill for what I want, the only questions I have at this point is which is the more durable device, or is there another device that meets my criteria that's built like a tank, but isn't priced like an Abrams M-1. If I had the money I would buy an SX-mini.. I don't.. Thanks in advance for any input!
