Which us their problem. It's hit or miss. Both the AL85 and Alien were pretty well done by Smok. There were lots of finish issues (QC Again) but the mods themselves were fine. I think they were among the more popular offerings they had. They even launched an Alien 2 recently.
totally on the point, i like the simple things, the AL85 is a interesting device, well made since i have taken apart 2 of them, and now still working, actually i did repaired one, my friend is kinda broke, so i did give mine for the time he needs it, it need to be repainted, and maybe a better cleaning, is working flawless,
the x-priv is not that great unit, i have broken and pretty damaged internals, rust, broken clips and housing parts, screen is fully working, i have it as spare parts unit, we dont know when comes another for parts or repair,
the main problem is well stated with smok mods and others, poor quality control, indeed, this brand have a great coverage of vape market but with bad or low quality products, is a famous brand with lack of quality....
Same for pods, is a Russian-roulette to get a quality product or maybe a long lasting one indeed, so, is better to stay away from them for a while!
