The Fuji may be both safe and reliable. Who knows? Any of these clone vapes have to overcome the bad rep that other cheap rip off vapes have achieved. It's hard to imagine you're getting high quality in a Volcano like vape for $100-150, and digital in this price range is really iffy IMO. S&B dropped the Volcano Digit warranty down to 2 yrs. from 3 for the Classic (analog), so that should tell you how they view digital vs. analog.

For a bag delivery vape, the herbalAire, Extreme, and new Zephyr Ion are much better bets, even though they cost quite a bit more than a Fuji. And all three will also do direct draw as well as bags.
