I have to ask, I have seen this all over the forums...and I like the looks but other than the 510 threading is this in any way better than say a volt or bloog? They seem to have more Mah, more voltage....and be cheaper?
One of my least expensive, yet best purchases.
Well,they could be like $10..up here I can get 1100mah batts with LCD screen for the same price...but yeah,they are a cool thing...size-wise.
I am unable to comment with regards to the bloog or the volt, as I have not tried them.
The SD stands for Screwdriver - the SD Keyring was designed by Trog - who designed the Screwdriver - the first commercially sold mod.
