I contacted both vendors about 4 hole atties. (vendors, I apologize if you didn't want personal emails posted to the public, I'm doing it to help inform people about your products so they understand what they are getting when they order).
Basically 4 hole atties are a myth. I and F must be misunderstanding as the battery has 4 vents but the atty itself only has 2 air holes.
What I said to abcig:
yes, on all the attys I've purchased from you they have had 2 holes above the battery connection threads. There has been talk on ecig forums about some people getting 2 hole attys from you and others getting 4. was the 2 hole design an earlier design and has since been upgraded or were the 2 hole design atties a defective batch? I would like to make another large atty purchase but I need to be sure they will be 4 holed. would you be able to send a picture showing the 4 holes? areyou counting the hole under the bridge and the one at the bottome of the battery connection as the other 2 holes? thanks.
On the forums people are saying that they are able to get 4 hole M602 atomizers from your site. All the ones I've purchased in the past have been 2 hole. has the design been upgraded? Am I able to purchase 4 hole M602 atties from your site? thanks
What abcig had to say:
The definition of holes on our atomiser has been based on the M40x series.
When you screw the atomiser and battery together, you will be able to see 4 holes around the gold band. This has been how we define atomiser holes on the M40x series so far. Since the threads of the M602 is reversed from those of the M40x, we are unable to create the holes on the atomiser of the M602 and therefore, it is done on the M602 battery. Nevertheless, when you screw in the atomiser and battery of the M602 together, you will be able to still see 4 holes surrounding the gold band. This creates the same 4 hole performance.
We have misunderstood your meaning and after further understanding, we realise that the 2 holes you mean are those on the atomiser threads. Please be assured that all our M602 (genuine) atomisers are the same design and there has been no upgrades so far.
What I said to elec-cigz:
there has been some talk on ECF about 4 hole atomizers for the M601/602. All the atomizers I've received from you have been 2 hole. I would like to place an order for 6 4-holed atty's.
Sean,
Both the 601 and 602 batts have the same amount of vent holes. The 601 atomizer on your site is advertised as having for holes:
M601/2 Ultra Atomizer Specifications::
*9.2mm diameter
*4-hole Atomizer design
Is it possible that the atties have been redesigned and you have some 2 hole and some 4 hole atties?
Here is the thread on ECF concerning the 4 holes:
4 hole atties
Interesting that you guys are getting a stiff draw. I am experiencing the opposite - a VERY easy draw. Where are you getting your atomizers from? I get mine from electronic-cigz which are 4 hole atties. Also haven't lost one yet - knock on wood.
Mine is also 4 holes and no stiff draw at all. My atties comes from
absolutelyecigs.com
all atomizers i have received from electronic-cigz are 4 hole. They also specify on their site that they are 4 hole. i believe the difference is an easier pull.
What elec-cigz had to say:
didn't realize that we had the wrong specs.
There is absolutely only one M601 Atty.. no different versions... no knock-offs
sorry for the confusion.
So there you go, case closed, props to Sean for being so direct and not beating around the bush. For those of you who somehow do have a M602 atty with 4 holes, are you sure its not an M4xx? Can you please post a pic of your rare bigfootesq atty?
