SD Keyring e cigarette (Ecig) review

Published: 3rd July 2012

The Best Electronic Cigarette

This is my review of a little product called the SD Keyring which is claimed to be ‘the smallest ecig in the world’! Hope you like it. Please check out my video review for a more in depth look.

I purchased the kit from .  The website was definitely one of the more professional ones I have seen with a massive range of products trying their best to tempt you. The website also operates a forum you can sign up to if you would like to get involved in their social community, chatting about all sorts of vaping related topics.  You have a choice of either tobacco or menthol flavoured cartomizers which are both 18mg of Nicotine.

The shipping took 4 days to arrive which isn’t the fastest, but as they say…..good things come to those who wait!

Presentation box / packaging

The SD Keyring comes in a formed plastic package which is simple in design and not much more. Some brief instructions are stated on the back including the usual, ambitious manufacturer claims regarding the amount of puffs you will receive out of each cartomizer which for the SD Keyring is estimated between 200 to 300!

Included in the box are the following:

  • 1 x battery 300 MAH
  • 2 x cartomizers (either tobacco or menthol, nicotine level 18mg)
  • 1 x USB charger
  • 1 x tethered lanyard

“This chunky fella stands up to the big boys”


In terms of charging, the battery screws into the USB charger which then plugs into your computer. When charging the LED on the USB charger lights up Red and once charged changes to Green.  I found a full charge was taking approximately 90 mins but once charged was lasting 4 – 5 hours of frequent vaping.


Switch (responsiveness)

The switch on the SD keyring was good and whilst needed a slightly longer draw than some of the other products I have tried, perfomed well overall. However I knocked a point off for this. Suppose it is a nice workout for the lungs!


Vaping experience

Putting the SD Keyring together couldn’t be simpler either, simply screw the cartomizer into the battery until you feel a bite and you can start vaping straight away. Once assembled I love the look and feel of the SD. Its chunky, oversized and probably one of my favourite looking devices. In terms of length, without the cartomizer it measures just 44mm and with the cartomizer attached is 89mm.

The battery is in brushed steel and has the SD logo on the end of the battery which is a nice touch.

The cartomizers are 510 thread so will be compatible with other 510 units. One thing to point out on the cartomizers that come with the SD Keyring is that they are not refillable (update - I have since managed to refill these. The top part on the cartomizer just needs a little more force than usual to remove)

In terms of vaping performance, I love this ecig. The amount of vapour produced certainly was on a par with some of the larger battery model. The throat hit was nice and the menthol flavour was pleasant but not the best I’ve tried. Where the SD performed brilliantly was the battery life. For such a small thing it seemed to last an incredible amount of time. It’s a turbocharged little firecracker of an e cigarette!

That’s really cool, I might get one. I could hang it on my keys as like something to have around if I forget my PV when I’m out. Good review

how long does it last before u need to recharge?

By KripDrip on 2012 07 17

Hi, I was getting about 3hrs out of the SD battery, sometimes more depending upon usage. Very impressive considering the size.

By Donny on 2012 07 17

Very funny review mate! I like your style. So, how would you compare this to the Vgo mini?

By Bry on 2012 09 10

Bry - The SD is quality ecig, performs really well and I love the look of it.. However the mini Vgo is my personal fave. It has a more powerful battery so it lasts longer and a switch which is almost faultless which makes for a truly brilliant vape. I would recommend the stainless steel model as its a thing of beauty!

If they put a ban on e-cigarettes why not ban actual cregiettas and other tobacco products which have been proven all over the world to be imperious to your health. It doesn’t make much sense to me besides the financial aspect of the argument. Time will tell if the e-cigarette still harms your lungs etc, but there is enough evidence so far that the nicotine vapor is nowhere near as harmful as actual burning tobacco smoke from the regulars cregiettas. It might still cause heart disease.
