The cool thing with Atmos is you can create your own 'custom' vape pens. They sell individual batteries and cartomizers, so you are free to mix and match. Back on the 4th of July, Atmos has a great sale, and I took advantage of that.
I purchased a 510 650mAH Battery, the 510 RT Cartridge Plus, the 510 Pike Cartridge, and it came with a free gift, the 510 Atmos A-Pen Attachment.
510 650mAH Battery
Battery Life: Pretty impressed with this. With fairly regular use, the battery will last at least ~3 days. It's nice to know I can carry it around with me all day and not worry about the battery dying.
Size/Appearance: Not too big, not too small. Fits nicely in the palm of the hand, and I'm a fan of the polished silver look.
510 RT Cartridge Plus
Size/Appearance: The cartridge itself is about 3/4 the size of the battery, but when attached the pen doesn't have too bulky of a feel to it. This is also a pretty cool looking cartridge. Although it is pretty basic, the 'high tech' look definitely grabs peoples attention.
Does It Work: IMO, this works a lot better than the Bullet Max Cartridge I have from Atmos. Get some nice big rips with this cartridge, full flavor. My only complaint is that I have already had to replace the atomizer for this cartridge. Luckily, they aren't very expensive. Note to anyone buying this cartridge, be careful cleaning it. The nice part at least, it's extremely easy to disassemble for cleaning.
510 Pike Cartridge:
Size/Appearance: I like the clear tank paired with the silver battery, plus it's easy to see how much ejuice is in their. The cartridge is almost as long as the battery, but like with 510 RT Cartridge Plus, it's not too bulky.
Does It Work: No complains whatsoever. I bought 2 tanks, 1 of them for nicotine e-juices and one of them for CBD e-juices. Considering they are ONLY $3, these are one hell of a bargain if you want to vape on a budget.
510 Atmos A-Pen Attachment:
This was a free gift with purchase of the battery, however I have not used this product.
Atmos can continue to expect my business!
No complaints on the battery, still can get 3ish days out of a full charge. But I've already gone through 2 atomizer's with the 510 Cartridge. As I mentioned above, they aren't super expensive, but the coil in the Bullet Max Cartridge while difficult to clean is still working without having to be replaced.
That being said, a friend that gave the 510 Cartridge a try said "This is the hardest hitting wax pen I've tried so far". So thumbs up from him!
