The SVD has handled everything i have thrown at it, including everything i've thrown IT AT! I have had this mod covered with sandy/oily substances from holding it in my dirty hands and riding shotgun unprotected in my pocket, quick scrub with a tooth brush and it was back to brand new every time. I've dropped it on carpeted floors and from low distances inside a few times, but today it really took a wallop The SVD plummeted to the pavement from a height of about 5ft today and landed with a straight THUD! It bounced around a few times before finally resting next to a bunch of kanger T3S pieces. The T3S didn't fare so well but that's expected, it hit so hard the tank snapped off at the base, even the coil chimney and flavor wick were thrown helplessly onto the pavement. However as if by magic when i picked it up there was about 1.5ml of juice still left in the top half for salvaging! However the SVD took this in stride. There were a few scratches from the mayhem but they are not even able to be photographed that's how insignificant they are. The center pin is perfectly fine(most likely due to the eGo threaded T3S which is why i use eGo tanks in the first place), the LCD screen is still perfect, and all of the buttons still function like new. I threw a spare T3S on it and vaped like nothing ever happened. Those who may question the quality of SVD's from fasttech may rest assured this is a quality mod!
