I like this a lot. It is easy to use, easy refill, does not leak in any way.

Produces much vapor, but can get rather hot at times:the vapor is warm and the mouthpiece too, but not so hot that you would burn your lips.

On the con side is the build quality of the coils. Two coils for start in the package. The first one lastet only two days and got burnt. The second one lasts now more than two weeks.

Refilling is easy and you do not get liquid on your fingers. Though the coil of course is covered by liquid, so take care when you lay it down when refilling.

Taste is good, lots of vapor compared to evod or gs air. When the battery drains, the vapor does not get less, maybe a little, hard to notice.

Clean taste, a small note of cotton that fades fast. I use 80%vg/20%water without any flavor and this works without problems so far.

The battery lasts about two thirds of a day, when you use it much. Pass through works good in case you run out of energy.

Would recommend it for starters and anyone who needs a small mobile ecig that will not leak and if the coil is working will do its job pretty fine.

No settings that could be messed up, as there are none except from the led light color setting.

Build quality is above average, everything fits, no visible failures and the silver version is all steal (except mouth pieces) so the color should last.

This is my second e-pen after the cheapest 2 ohm ego pen you can find on ebay, so I'm not an experienced vaper. I don't vape a lot.

Build quality is hands down excellent. The device looks cool. It's small so you can easily take it with you if you are going to do sports. No leaks whatsoever! Great clouds. I've been using it for a couple of weeks—same coil—and it's still good.

The taste, compared to my cheapo pen, is super clean. I sorta liked the not so clean taste on the previous pen, so I'm going to try 1 ohm coils with AIO to see if it makes a difference. Also, the only locally available 70/30 juice is definitely too strong for this pen, but hey, you can do a couple of drags and it will feel like you've just smoked a red cigarette. People don't like that, but I sorta do.

Some condensation builds up on the mouth piece fairly quickly, so you'll have to clean it from time to time. Not that much of a problem. Also the vapor can get a tad hot if you do several drags one after another, which I don't do often anyway.

A great device, especially for the price. Nice packaging makes it a perfect gift for a smoker.

Purchased this as an alternative low profile vape simply because it was so cheap.
The supplied 0.6 om coils work ok providing plenty of vapour.
I tried out the three coils supplied with the Cubis, the clapton and 1 ohm coil were underwhelming, but but the 0.5 ohm coil worked really well, it allows more airflow than the supplied coils and makes heaps of vapour.
Overall this is a really nice low profile mod that is easy to use and fill, makes plenty of vapour.

The main problem for me is that Airflow adjustment which don't working. I tried to set up on different position, but every time I get same results. I may contact support for that.

The second I have very pleased of them I think better result with 0.5 ohm coil head
best buy for the price GOoo

Such a simple device but works perfectly, great for beginners or advanced, packs a punch, no leaks and the added bonus of disco lights is just fab!

It's the best thing one can buy for the price!

I have purchased so many of these for me, family and friends, I have lost count. They work very well with .6 authentic joyetech coils. I try to buy extra ones just in case they quit making them.

Good starter kit, easy to use, easy to fill, no leaks and good vapor production.

I have been using the aio kits for a while now, and I love them. They are so easy to use. Easy to fill, no leaks and good vapor production. I also like the Joyetech d22 xl to use when away from home as it has higher battery capacity and holds 4ml of liquid. You can't beat Joyetech quality. I use all resistance (.6, 1.0 and 1.5 ohm) coils depending on the e liquid I am vaping. I highly recommend this kit to beginners and experienced vapers alike.
