    I own many rta's pharaohs,Vaporesso, Springer just to name a few but I always go back to the engine. I've had mine for several months now. No leeks best flavor dense clouds, doesn't get hot and easy to fill I've carried it in my pocket and still no leaks, easy coil builds and wicking. However I suggest coils no bigger than a 2.5 and dnt over stuff when wicking. A must have for the RTA lovers. Direct vapor has the lowest price I could find anywhere. Wish it had a bubble tank that's the one con I have

  6. The truth review by frank on 10/7/2017

    I purchased this RTA here and have owned it for about 3 weeks now, I use it daily. It performs very well, easy to rewick and replace coils, flavor is good, no spit back, definitely NO leaking, air flow is perfect for me and adjusts easily, and it has a good looking appearance. I like the fact that it doesn't have juice flow control! I give it 4 stars because the thickness of the threads and material on the deck is too thin, when reassembling the tank to the deck it can be tricky and patience testing!!! It doesn't thread back together easily or smooth like some of it's competitors!! My second reason for 4 stars is the top of the RTA does not come apart at all! Makes it more difficult to clean and dry it out!! If these 2 flaws where redesigned this RTA would be 5 stars plus!!!

    Received this a couple of weeks ago. Used the coils that came with the atty, wicked it up, and bingo. Been vaping at 70 W and zero problems. Good taste, no leaks, no dry hits, good capacity. Very happy, and it looks like it was made for my Sigeli Kaos.

  8. What they're sayin' review by Douglas C E on 7/31/2017

    I ordered this RTA, Ever since I got over the nervousness over building it, I've been using it nearly non-stop.
    I love the rose gold, the slide up collar side fill is excellent, and has never leaked. The coils keep on going. This was my first experience with Clapton, and my first wicking, no problems other than getting it aligned and threaded after building it. It takes Patience, If you get mad, set it down, take a break, and come back to it. It really Does give juice more flavor. What they're sayin' is true. The speed of delivery surprised the heck outta me. Excellent Buy, Great Job D.V.

  10. Outstanding RTA for Large Air Flow Vapors review by Tinman on 2/24/2017
    Overall Rating

    I have both the 22mm & 25mm OBS Engines. This atty is best built as a duel coil Clapton Wire (or big wire coil build) atty, it is not designed IMO to give its full potential with single wire builds. It DOESN'T LEAK...PERIOD...NOT EVEN ANY OVERSPRAY !!! Flavor is very good (8.5) for a large air flow atty with air adjustments for personal taste. Vapor is full and thick. I use a Kepler heat disapater but it's not necessary. It's my top winner compared to many other large air RTA'S touted as "great ones" in my collection. OBS Engine blows them away in every aspect...the top air flow does not hinder flavor. No dry hits..and easy to build (wide open deck)...I use Muji or Native Wick Cotton. My builds is a 3.5mm/duel SS coil/ Duel core clapton @ 2x30ga x 40 ga/ 2.5 Ohms.....my preferred wattage is 66-72 on a Triade DNA 250. Hope this all helps but this atty is a winner....VAPE ON MY FRIENDS AND VAPE SAFELY !!!!!!!

    A beautiful eye catching design is what struck me first, wicking it is a bit tricky, but the flavor is superb.
