So once again I’d like to thank Anita from GearBest for sending this mod to me for review .
First impression of this device was that it was extremely heavy . It feels very sturdy like if you dropped it on the floor you would dent the floor and not the unit itself ! It’s also smaller than I thought it would be .
In the hand it feels very comfortable , the rubberized coating on the outside makes it very grippy. I think if you were ever being mugged this mod could be used as a weapon it’s that solid . One thing that bothered me at first was the location of the fire button . I was constantly pushing on what looks like a button at the top 
The 510 is a fixed pin which some would argue isn’t desirable , but what Heatvape did was genius in my opinion . The 510 is separated with a connector cap that you screw the atty onto , then screwing the cap down makes perfect connection and the atty sits flush on the invader . 
All of the atomizers I tried sat flush and made good connections . From what I’ve read the reasoning behind the fixed pin is that it’s a Temperature Control mod and a lot of the Chinese manufacturers found temp control more stable with a fixed pin.

Temperature Control
So this device is equipped with Temperature Control. I’m not gonna go into how temp control works as by now most will have read about the ins and outs of it . I also can’t say what chip they use as they don’t list it anywhere on there site.
It functions the very same as the Vapor Flask clone maybe even a little less finicky. In fact I’ve not experienced any negative issues with the invader running in temp mode .
I first tried it with a manufactured ni200 coil in the GCT tank from Smok and that worked flawlessly. I vaped the tank dry and never got a burnt hit . I also wrapped my own nickel coil on my Lemo 2 and had the same result. 
Only negative about temp control is that it seems to use more battery life than reg wattage mode . I burned through two samsung 18650 in record time , less than a day ! Not even really heavy use . I should also mention there is no on board charging due to the waterproofing I’m thinking . So what I’m saying is don’t leave home with out a spare battery or two .
I won’t go into reg variable wattage mode too much as it works as it should . One slight issue is that in reg wattage mode it has a slight firing delay but it’s maybe a second so really not a big deal .
Pros
- Durability- this mod is the most solid I’ve ever handled
- Functions- functions flawlessly in with every setting
- Size - it’s small enough to drop in your pocket ( however it may look like some kind of bionic penis so hopefully you have a shirt pocket lol)
Cons
- Battery life - very hard on batteries
- Button placement - would have liked to see the fire button higher on the mod where they have the kind of fake out button
- Sleep mode - this mod goes to sleep very quickly which I find a tad annoying .
Conclusion
Simply put …this mod is awesome . It’s exactly what you need for a beat around mod . It can take a lickin and keep on tickin . If you search on YouTube there are videos of this mod getting run over by cars and dropped in sinks of water and it’s because it is a well made quality product .
Anyone in a trade or that works outdoors and vapes needs one of these mods. For 60 some bucks for a 50 watt temp control mod that is made this sturdy it’s a steal. Go get one !
