I just got one. Ended up having to rma it though. The screen was all wonky on mine. For the day I did use it it was great. The single button menu threw me for a minute. Been using a vamo v5. After figuring out why I was always adjusting watts instead of firing the
device it was great. Comparing readouts to my vamo, pretty much identical. What the vamo read in resistance and battery voltage, the sid read the same. I don't like that it is so light. Subconsciously I relate weight to quality. This probably isn't the case, but my vamo is heavier. Now my VTR is whole different animal. It's just a shiny beast, but that's another story. All in all time will tell on the sid, but first impressions, I'm satisfied with it for the price point. I got it Super cheap though. Even with the return shipping for an exchange, still under 30$.
