I'll admit, the 510-t is a very reliable atomizer for a tank. Prior to this, i was using only std Ego-T type A attys and they hardly lasted past 3 weeks before it was too hard to use it again. I also believe i'm a fairly heavy vaper (5-7 mL average a day).
I've been vaping my 510-T for a bit over 2 weeks now for one atty and it has not shown any of the symptoms that the ego-t type As have shown me, (clogging, lots of gunking up, taste decrease, etc). I have cleaned it once with just microwaved filtered water and still worked after. I do recommend blowing the leftover juice (from the battery side) every night before going to bed or when not using it for a long time to prevent possible drying and gunking of the atty. I do have another one but I believe it is a faulty one and currently trying to get it replaced with a new one (tank comes off REALLY easily, leaks up the ying yang, and very tight draw). Another good thing i noticed is that the tank holes are bigger on the 510-T tanks and I was easily able to just use a dropper bottle to fill it up through the hole. One peeve i have though is having to refill the tank A LOT. I can easily go through a tank in 30 min with the ego-t type A tanks so you can kind of see how many times i had to fill up the 510-T tanks (standard tanks). I do notice though is that the atty gets REALLY hot after 2 or 3 toots so it would not be good for people like me with the PV glued to the hands and mouth 24/7 HAHA! Overall, if you are a light to moderate vaper, i HIGHLY recommend it. Heavy vapers, i would suggest staying away just because the juice capacity is way too low and heats up way too fast (risk of popping a coil early if not careful about taking breaks) to satisfy a heavy vaper.
