The 4081 rocks!!!

I still love it although I primarily use my 510 all the time now. I pretty much lend my 4081 kits out to people interested in e-cigs. It's a great starter e-cig and is great for beginners. However, once you get used to vaping, the best upgrade after it is the 510.
How much bigger is the 501 cart compared to the 4081?

I seem to always have a problem with batteries that get stuck "ON" though. It has happened with about 8 batteries and i just chuck them in my spare part box. Anyone get that? I'll be vaping and like every puff the LED just stays on and then times-out and blinks. It's useable but its soooo annoying, how do you fix this?
I have a few like that. You can reduce the problem by giving a quick very short puff to reverse the air flow right at the end of a long drag. It doesn't take much. It does take away from the relaxed smoking experience a bit though.

I use 4081 daily as well. I only use it for dripping, connected to a USB power supply or battery pack. When dripped you get full juice flavor, man the morning coffee tastes great, the evening RY4 is even better.

Not much good for me and travel or work, but for dripping it works great. Three drops and I get clouds of vapor.

I purchased my first njoy kit in Feb this year, I have never had a failure. Currently I have many ato, batteries, chargers, carts, and several pass thrus.

I will never give it up!

I love mine.. I have 2 901's (1 white / 1 black) and 2 4081's (1 white / 1 black). I tend to find myself using the black 4081 all the time. I'm also having really good experience with battery life. I have a 2 hour roundtrip commute to work, then 6-7 hour workday, and 1 battery lasts me the entire time. Throw the 2nd one on for home use, but I find that my commute to/from work is where I do the most vaping. I do have a 510 on order, based on all the good reviews I've seen on it, but I'm sure I'll still throw the 4081 in my pocket on a night out on the town.

I don't drip however. I keep a small baggy with me with a couple of filled carts, never counted how many puffs I get off of a cart, but I use about 4 filled carts per day. Carts aren't that difficult to fill, I pull 4 empty ones out at the beginning of the day, line'em up in a row, fill'em up, put in the plug, throw'em in the baggy. 5 minutes total time for the day, and I'm good all day.

My 901's are basically just backups. I got them after reading how great they were on here, but honestly I can get just as much vaper production out of the 4081. The only plus I see on the 901 side is that the carts seem to last a little longer.

So, just chiming in here to say that the 4081 is indeed under-rated. Yes, it's a monumental rip off in terms of buy in price... but if you load your own liquid and experiment with your vaping technique, the 4081 can actually be made to perform very nicely. I can get mine to produce a lot of good vapor, a nice throat hit and a fairly consistent experience. The drawbacks are relatively short battery life and the miniscule carts. Personally, I'd estimate that the 510 carts are more like 3x the size of the 4081's. But all that really means is that you have to top off more.

Bottom line: if you own one of these, don't feel like you got completely scammed. It's a good starter unit that can be very satisfying if you take the time to learn how to use it to optimal effect.

I have a soft spot for my Npro since it was my first unit,but its not my favorite one by any means. The original Npro hardware still functions great with no returns. Battery life is great.
Drawbacks as follows:

It cost me 80 bucks and the cheapie kits I bought for "spares" have inferior fit,finish,and performance.

Carts crack easy..Especially the black ones for some reason.Npro carts seem a higher quality, but its almost cheaper to smoke than buy those.

The fluid capacity is a cruel joke.

Filling the carts properly means disassembling the cart basically and its a pain.

Inconsistant draw. Primer puff,hit (weak), hit again (OK..maybe),weak...rinse,repeat.....

Topping off a cart usually leads to juice getting by the filter.From there you have to waste juice blowing it out or TASTE raw juice.
I couldnt stand that taste and have NEVER had to experience it with my 510.

Auto batteries like to hang up at times for no reason causing a heated sensation in my pocket! And no im not refering to the cleaning cycle.

Auto batteries are susceptible to juice ruining them.

Primer puffs are a waste of everything (time,juice,batt life..etc)

Some stuff and i can live with,but the high initial cost along with the filling/capacity issues are dealbreakers.
Im not sure how old this design is,but theres just other models out that are superior IMO and the prices are dropping!
All 510's are basically the same as an example and some starter kits are well under 50 bucks!

I recently bought an NJOY NPRO at a Smoker Friendly retail outlet locally. It was sort of an emergency buy (was going on a week-long trip and had misplaced one of my two Minis) but I have to say that I'm impressed.

My biggest gripe is that the carts suck. Not only are they too small, when I went to refill one, I noticed that there was this rubbery glue-type-stuff all over it. Opening some more carts, I noticed that maybe half of the ones I got with my starter kit have this same glue stuff all over them. Some just on the bottom (to affix it to the mouthpiece, maybe?) but some INSIDE the filling! Yikes! Not something I want to be vaping.

In any case, I've been carefully dripping with it for the last week and a half and I have to say that I prefer it to the Mini. The vapor and throat hit from dripping is definitely what I needed to kick cigarettes for good.

Although I'm pretty sure I'll soon be buying a 510 along with everyone else on this board...

I am really starting to think it is. I am doing a 'puff' count on my batteries and my 2 month old 4081 battery lasted twice as long as the 510 and within 30 puffs of the 401 and thats with the switch sticking 'on' a few times during the counting. Also after 25 puffs on the 510 it dropped in vapor production to about what the 4081 did through 130 puffs. Granted I easily paid twice as much for the 4081, but that was just me being uninformed at the time.

The consistency SM is referring to is why after my 901 test run I have opted to go back to my RN 4081.

901 is a temperamental bi+#>. :(

RN 4081 is a sherman tank!!

I just ordered a new 4081 from ecigarettecigar on sunday. I had planned to get a joye306 and replace the Npro I use at work, however; I saw they have something they call double capacity carts for the 4081...If they are what they claim, that could change things dramatically for that model. So I'm very much looking forward to seeing these new carts...I will post again once I've gotten them and done some testing.

I agree that it's pretty solid. I wonder if there's a cart mod that can make the capacity of these bigger? I think that's really the single serious drawback with the design.
Hey SF, my friend Hayes at Digital Smoke Shop, ecigarettes has your answer?

He swears by them. The only holdback(superficial) is taht he only has brown:(

I am about to get some.

Oh, and he says they are super easy to refill:)))
