Just recently picked up a couple of Nautilus AIO as pocket friendly carry outs - they are nice and slim, very lightweight and work reasonably well - alright they don't produce huge amounts of vapour, they can be a bit "spitty" especially on a full battery charge, they are a pain to fill in a hurry, rather a warm vape BUT they seem fairly well engineered and do the job.
According to Aspire they are only suitable for the 1.8 and 1.6 ohm coils and I can see why - the centre cup of the coil holder is not large enough to accept the bigger bottom pins of the other coils as well as allowing airflow - 1.2, 1.8 Clapton and 0.7 ohm etc.- which is fair enough.
Trouble is I have just bought 2 packs of each of the 1.6 and 1.8 ohm Nautilus coils and they seem to have now changed them again - they now have the larger diameter (and bigger air holes) bottom positive pin so whilst they WILL physically fit they completely cut off the airflow! They will NOT work with the Nautilus AIO !
Yes, the "scratch and sniff" tells me they are all genuine. These have a batch date of 1806284 whereas my stock of older coils (same box, same labelling and description) but a batch date of 1709180 have the smaller bottom pins so these do fit. Strangely enough the coils that came with the AIO also have the small pins?
Now before somebody chirps up with "just change the bottom pins" - you can't do this satisfactorily, because the pin, insulator AND the base of the atomiser are a larger diameter than the old ones so if you try to fit the smaller pin and insulator it is very loose and likely to leak or at least not clamp the wires effectively giving erroneous resistance readings to the mod.
It makes me wonder how many production lines/facilities Aspire has producing these coils and whether they are all singing from the same hymn sheet?
Some time ago we had the fiasco of the wonderful ceramic wicks in the original BVC coils - that was "swept under the carpet" and suddenly ceramic was out and cotton was in. Then they decided to increase the size of the juice ports in the atomiser - presumably to satisfy the needs of the trend for high VG blend users? Trouble is, for anyone that wanted to continue using a higher PG blend the end result, in Nautilus and Nautilus Mini, was gurgling and/or flooding - at least they still worked wonderfully in the Kabuki but consigned my Nautili to the vape drawer.
Now we have new Nautilus coils THAT DO NOT WORK in the latest Nautilus device - priceless! I've wasted my money again!
Oh, and I don't expect a reply from ANYONE at Aspire - why break a tradition!
