Here is my review of the Versus 510.....and I purchased 2 Copper kits.
FEEL (5) It is extremely light. Much like the DSE 901. Can hold in my mouth and vape using the automatic battery.
DESIGN (4) The design is ok. Really like the whistle tip cartridges, only wish they were a bit flatter and not so dense.
INTEGRITY (3.5) The draw on the Versus is easy and consistent. The batteries are much like the DSE901, short lived....but, they do charge rather fast. The only thing I can complain about is the atomizers, which IMO are not performance friendly. Like I stated above, I purchased 2 kits. In one kit one of the atomizers was DOA (have spoken with Eric and he plans to replace it once he returns to the states on Friday). The other kit had an atomizer that had the most horrible, and I DO MEAN HORRIBLE taste that I have ever experienced! It had a really gruff-bottom-of-the-barrel taste! Sort of like vaping from a fiery red-hot welding rod!!! It was the most gosh-awful taste I have ever tasted!!!!!!!!!!!!!!!!!!!!! I tried blowing the atty out and letting it sit overnight. No cure. Was constantly having to drip directly on the atty for it to produce a decent taste which only lasted for about 4 puffs and then back to the awful gruff taste that it produced. I finally replaced it with the spare atty that came with the kit and it has performed as an atomizer should. Can actually taste a flavor from the e-liquid now, even without direct dripping. MUCH, MUCH BETTER!
VAPOR PRODUCTION (5) The Versus has an unmatched vapor production compared to any other e-cig I have owned.
THROAT HIT (4) To me, that all depends on the juice and the strength of nicotine you use. I use 18mg strength and dilute with vodka, which produces a throat hit that satisfies me. IMO, the DSE 801 has a throat hit like no other e-cig, no matter what liquid or strength you use.
All in all, the VERSUS 510 is an excellent choice for vaping. I have heard so much good things about the 510, so decided to purchase and decide for myself. The reason I decided to purchase from Eric at Vapor Station was the fact that these kits came with 3 batteries. Even tho I had a bad experience with 2 atty's, I know that Eric will make it up to me in the end.
