RN4081 is one of the original designs from ebay and is still available off ebay.

It runs cooler than my new 510 atty. 510 produces more hit than standard RN4081. But my modified RN4081 can keep up with 510 pretty close.

I hope the 510 will be durable; time will tell. I don't use the 510 much because I don't want to wear out the batteries too fast.

I think the secret is to stop vaping when you feel heat building up and to direct drip to insure element is always wet.

I have been doing a lot of steady vaping with the old RN4081 since I built my 4.4v/1.5A pass thru a couple months ago.

I just read thru all the posts. Now I am scared. I had no idea atomizers could fail so often. My RN4081 just keep going like energizer bunny. Maybe because it runs colder and produces less vapor?

Sometimes my juice is to strong for steady vaping so I will direct drip a drop of H2O to weaken the hit and nicotine overload. I have no idea if that improves life of atty?

Maybe the only posters here are the ones experiencing atty failures?

I am really worried about my new 510 because it runs very hot. I think thermal stress is not good for any heating element. Now I am afraid to use the cartridge on my 510 now because I had so much luck with direct drip. Problem is the RN4081 is better for direct drip because you just cut 1/2" off end of cartridge.

I need to figure out how to direct drip 510 and not have to touch metal with teeth. I like to direct drip from end without removing cartridge.

generic RN4081
1st - 3 weeks, heavy use, dripping only
2nd - 20 seconds, died with the battery
3rd - 1,5 months, heavy use, dripping only

1st - standard batts
2nd - standard batt
3rd - nicobox mod with 14500 and direct USB when on computer

1st - puffed, then after puffing again was dead (coil was shot 3mm near the joint)
2nd - puffed and it remained on without noticing
3rd - still going great

1st - occasionally blew air and overnight drain
3rd - just (2-3 times/week) burning it red hot then blowing air through batt end

bought locally bottles that looked like the ones from ruyandirect, different aromas.

Heater coil looked black, charred and full of gunk on the first one, clean on the second (d'oh) and pretty clean on the third after 6 weeks usage. Pretty clean means coil is clean, mesh is full of gunk and charred.

Do you let your RN4081 atomizer get very warm to the touch?

I have a Janty Dura-C, had it for about a week now. 1 atomizer was producing poor vapor, 1 good puff and after that it diminishes almost entirely, so I exchanged it for a new one which did almost the same thing, just a bit more vapor.

So I decided to do a test before sending it back again. Like the manual explains, I gave it a good wash with some water and dried with a hairdryer, then left it for about an hour. After I topped up my cartridge and gave the atomizer about 3 drops of juice it worked perfectly.

I also washed the one I was using during the week and the taste and performance is much better. Maybe some of the liquid in the atomizer doesn't burn, which would make a sticky, bad tasting mess in there?

An atomizer can foul out just like a spark plug. Crud builds up between the positive and negative components of the atty. To correct the problem, use a tooth pick to scrap the crud out then rinse with distilled H2O and dry.

Clear as mud I know.

The area to clean is on the threaded end of the atty. It is the 5 mm crevice between the threads and the 2 mm hole that talks to the battery.

Gamucci classic atty, went strong for about 2 weeks. Then I tried to dry it out by running it continously on my 6100mAh monster pack, withouth a cartridge installed. It went for 40 seconds, than it died .

Never try this at home...it will kill your atty.

Replacement atty's are 801s...none of them matches up the performance of the gamucci

a) 2 RN4075 atm - each lasted around 3/4 days. Now resistance shown is open circuit.
b) 1 901 atm - lasted around 5 days. Towards the end, i was vaping heavily and maybe the atm was running hot on this one. Resistance shown now is around 50 ohms.
In both cases the deivice is SD.
c) 801 atm using usb manual PT with battery - more than a week of use (only in the evenings) - no problems yet.
BTW, how do i dismantle an atm to see whats wrong?

Just bought a Prodigy V1. Seemed like the cartridge was too far from the heating element to get the kind of vapor production shown in the videos. So I started dripping. In quick succession--about an hour or two-- four atomizers (my only 4) stopped working. The heating elements no longer heat. I tried cleaning, changing batteries, blowing out the excess liquid, and even sucking out the excess liquid with a vacuum cleaner duct tape. The atomizers remained cold--both with the Prodigy and with my old classic SD. One of the atomizers (the one that came with my V1) was only a day old. The others had been used only a few weeks (with frequent switching).

Please help. I'm without the means to vape right now and will soon have to purchase cigarettes.
