I have a DSE905 V3 (the one with the blue led). Anyways, I thinks it just "OK" with cartomizers. I needed to get a 901 to 510 adapter + a 510 to a 808 adapter. I closed all the holes on both adapter since the draw was way too light. That improved the vapor production a little. But there is hardly any taste or flavor.
The 905 is voltage regulated at 3.7volts. Under load it's about 3.5-3.6 volts which is not enough in my opinion. I bone my 905 to fit 2 x CR2 batteries and the
vaping is like night and day. 5 volts is the perfect voltage for vaping.
Now, if you had a 5 volt mod.. then cartomizers are a dream. Cartomizers with my Prodigy V2 = awesome.
By the way if anybody is looking on buying a spanking brand new 905, PM me. I received it as a replacement from Health-cabin since the original one broke.
My DSE905 is modded to fit CR2 batteries for vaping heaven at 6 volts.
