According to Jim Davis'
E-Cig Model Identification Guide, the Gamucci Micro is a DSE103:
And the DSE103's exposed wick atomizer certainly does
look like the Gamucci Micro reviewed by Scott Bonner (igetcha69) back in January of last year:
[You could partially confirm that by measuring the length of what you have. If it is 103 mm, it probably is a DSE103 (or a knock off).]
If so, you can order replacement parts and cartridges for it from
BestEcig or
Heaven Gifts in China. I don't know of any U.S. supplier. Learn more about the DSE103 by searching ECF for that term, e.g.,
this search.
Be that as it may, you can refill the cartidges you already have with
e-liquid from any of the fine suppliers represented here on ECF. That is
much less expensive (and with a huge range of tasty choices and nicotine levels) than buying more carts. Or you can forget the carts and just drip the
e-liquid directly on the atomizer as Scott demonstrates in that video.
Sooner or later you probably will want to switch to a better e-cig. If you like that exposed atomizer concept, try the M401/M402/M403 series. [The 98 mm M402 is close to the same size as your Gamucci Micro; the 108 mm M401 is a bit longer.]
Otherwise, I recommend either the Joye 510 or Kr8. Both are excellent (but very different) models.
Check out my WWV Illustrated Guide to learn more about all of this (including the
e-liquid).
