This RTA is Phenomenal & the machining and threads are beautiful! Comes with single & dual build decks that are both huge for big exotic builds and or regular coils. In fact the single deck is a gentle giant. Also the flavour is very very good for a 25/26mm sized tank.
My 510 screw came with the flat head cut way of centre so it was breaking down very fast from continually swapping the two decks out.
However I emailed Cthulhu with a picture of the defective 510 screw and they are sending me out a replacement no questions asked!
What a great company! Cthulhu really cares about there product & customers. I can't fault them what so ever!. Once agin I cant stress enough what a great company Cthulhu is! I love this tank as it's perfection. I can highly recommend this RTA. 10 STARS!!!

Самый лучший бак для меня, с намоткой можно размахнутся, но жрёт как не в себя

I've had this for about 3-4 weeks by now and I really tied a lot of builds, Juices and wattage modes on this to try to get the performance to where it should be ...

The perfonrmance itself is just fine .... It's cloudy, it tastes good and it's a really nice vape.

BUT:

Aside from the things I mentioned there are a couple of things that reeeeeeally need to be adressed by Cthulmods:

First of all .... Get your threads to perfection ... the threads on this device aren't totally crap, but for the amount of material used they are not smooth at all ... even at this pricepoint (comparing to Geekvape products)

The orings on this device are not only instable ... they don#t even fit in the places they're put in ... meaning you have a loose juiceflow control, a falling off drip-tip and potentially a shorting 510 ....

Get the airflow on the single-coil option correct ... they really did a good job on the dual coil, but the single coil option is just pathetic ... far away from direct airflow ... and rather remembering me to sucking air through a siver .... not smooth at all and definitely something that needs to be fixed to even call this "an option"

Get your wicking right! .... it would have been easy to put a good method of wicking in this RTA .... unluckily ... there is some kind of a rashed and not well thought out wicking solution, that just contradicts the size of coils you should build in this RTA ... also don't expect to wick 70 VG or higher ... as the space between chimney and glass is simply too small and airbubbles just get stuck in here ....

Also the airflow-control is kinda loos .... which is due to the bad orings on this device

I have been using several V3 RTAs for a few weeks now and it is really impressive - build quality is excellent, the two-coil deck is massive with top quality screws that should hold the most exotic wires firmly, and all component parts of the tank are built to a very high standard.

For flavour chasers it is probably best to use the included single coil deck, which is very easy to change and gives excellent flavour, REALLY excellent! I have probably put 10-12 of my favourite e-liquids through my Cthulhu V3s, and it can be a surprise when you start discovering new flavour notes in a juice you thought you knew very well, and that has happened more than once.

I only have one complaint about what is otherwise a great RTA - WHY does Cthulhu Mod make the claim that it holds 5ml, as I can assure you that it most certainly does not! That apart, this tank should be on the list for anybody that is looking for excellent flavour delivery, and as a bonus it looks smart and is built superbly.
