The MK 1 is manufactured by and sold by Trog and Co.
It takes a un-protected 16340 Lithium ion battery which equates to 16mm x 34mm .
It comes in a choice of 3 models
901 Mini
510 Titan
801 Penstyle
It also has a choice of Colours - Silver - Black - Gold.
The Black is now a smooth shiny black and not the matt textured one on the last model.
You have full support and if any problems arise there is the option to have them returned to base for a refit regardless of the age.
The SD MK11 is manufactured in China to Trogs specifications.
The body is slightly larger than the MK1.
It has a protected 18350 Lithium ion battery which has a longer run time than the MK1 battery.
Comes in Silver which I think is more shiny than the MK1 andalso in Black.
It has a 901 fitting but you can buy an adapter to use other atomisers with it.
The SD Forum will give informational support for this model but they will not do repairs.
Totally Wicked and other sellers who are selling this item must deal with replacements and repairs.
I never bought a MK11 - I never needed one but yes I am curious as to the finish compared to the MK1.
The body parts are not interchangeable with the MK1 - so as with so many other purchases you end up with 2 ecigs to maintain.
The Battery life on the MK1 is more than sufficient and knowing I not only have support but also somewhere in the UK to send it for a refit if something does go wrong wins it for me.
The turnaround for repairs is fast - as soon as they receive it they set to work on it and get it back to you in the next available post.
They do both use the same charger and atomiser but that is about it.
Both are pretty well protected from faulty atomisers making the battery go Booom regardless if it is protected or un -protected it can still go boom.
No one to my knowledge has managed to blow up a battery in a single battery device , and no one has ever blown up an unprotected 16340 battery in the SD - T rog has tried to blow up the MK1 with over volting and sending the battery in to deep discharge but he was not successfull.
I should add he put the SD MK1 in the garden while he tried to achieve this ...... we waited all night for the Kaboom report but it never came.
Please don't try to do it inside your home
