The CDA by OMG
Wow the OMG CDA is a clever little thing!
This is a CDA – no idea what the C stands for but this tank is a RTA and an RDA in one and you can switch between the two by simply twisting the tank!
If you find RDA and RTA confusing have a read of our guide here!

Please note the OMG website – even when translated is pretty hard work – I am struggling a bit, but I will try to decipher the facts that I can!
Basically when you twist the tank it closes off the E-liquid flow so you can use it like a dripper (RDA). I think you also remove the tank top part – but not 100% sure!

There is a Bayonet top fill design for use in RTA mode which promises no leaking.



The OMG CDA comes in 3 colours – Power Silver, Phantom Black and Smart Blue.
Kit Includes

Anyway the bottom line is this is a convertible tank – you can use dual coils of many different types and switch from RDA to RTA if you want to!
I do really like the styling of this – the “Power Silver” has really caught my eye.
The one thing I am shocked about is the price! You can get a big name RDA or RTA for a lot less and I am looking at Pre-order prices which are usually lower than the full retail price.
If this was cheaper I would give it a bash!
Do you think you would find the CDA useful or really CBA with it?
