hi all,
over the past week i have reviewed both the Screwdriver mk2 as well as the DSE 905 so i feel i can speak fairly regarding both
devices.
Screwdriver mk2 review:-

DSE 905 review:-
http://www.e-cigarette-forum.com/forum/video-reviews/51830-hi-def-dse-905-sd-clone-e-cig-review.html
here are my thoughts when comparing the 2 devices:-
1. both have equal excellant battery life but the SD has specially made protected batteries
2. both produce an equal amount of vapour........the same amount as a regular 901 (though the atomisers included with the SD were not the greatest, when switched to a different 901 atomiser the vapour is extremely good)
3. both have a equally good throat hit.............but nothing too amazing. (both devices produce a better throat hit when not using the supplied atomisers)
4. both look very nice and feel comfortable in the hand. though the button placement of the SD is far superior in my opinion. but that could be because its almost feels taylor made for the size of my big hands! lol
5. the 905 has the "ring of light" around the atomiser which acts as a visual indicator to let you know that the device has been turned on, its activating, the cut off limit reached and the battery needs charging. personally, i love this feature of the 905 and think it also looks great.
the SD has no indicator or led etc.
6. the SD has a very simple cap that can be placed over the button to prevent accidental activating. it obviously works extremely well, but i dont use it myself as i dont like it hanging via the small lanyard which attaches it to the body.
the 905 has the addition of an on/off switch which in principle is a good idea..........but as much use as a chocolate teapot! the on/off button is very easily pressed in and out and when its in your pocket then it constantly turns the device on and off anyway.......a simple sliding switch would have been a far better choice. however, i must point out that its only turning power on to the device and NOT actually activating the atomiser. so in other words, its a good idea to have the on/off switch....... but utterly useless! lol
7. the actual thumb operated button on the 905 does the job fine, but like someone else mentioned in this thread its just the same as on any other manual battery powered e-cig.
the SD button is obviously much larger, but feels like a far higher quality and for me is more natural feeling to use.
8. the SD in my opinion is built to last. the actual quality of the unit is excellant and when you unscrew the 2 halves there is not a drop of solder or any wires on show. the button also is completely wireless and solder free (in fact, i think the whole device is)
its slightly fatter than the 905 and the actual shell of the body is a thicker metal than the 905 too.
the SD looks and feels like a top quality device that i feel confident would last for many years of
vaping. and if the worst happens and a part needed to be replaced it could be done so quite easily.
the 905 does not have the "feeling of quality" like the SD. when taking the 2 halves apart you can see bits of plastic, glue seeping out and bits of solder slapped to the inside of the body which has a VERY thin wire attached.
the on/off button is very suspect in terms of quality and i could imagine it being the "achilles heel" of the 905. the other thing is that if something did go wrong with it then you would need the soldering skills of Cisco to fix it.........and that would be depending on if you could get hold of the parts.
9. price is obviously a very important factor here, and the 905 can be purchased for around £50 cheaper than the SD. but in the defense of the SD, it is a far higher quality plus comes with the protected batteries, 2 atomisers and a bottle of
e-liquid.
does that make the SD worth the extra money?
well thats not for me to decide.
in summary, i feel both devices are very equal in performance.........and both perform very well indeed and are a pleasure to use.
but if i was going to be stuck on a desert island for 2 years and i was only allowed the option of taking one of the devices with me then i certainly know what one i would choose to see me through.
(i should point out that the desert island has a mains power source and a little shop that sells e-liquid and spare atomisers

)
i was going to make a video to show the 2 devices going head to head........but i dont think i need to bother now! lol
all the best,
cheers,
scott
