No 901 atomizer with Bartleby 3.7v?

[Placebo Effect]

I just bought this mod from a forum member, and it arrived today. I've been using a DSE901 for months, and when I was Googling the Bartelby, it appeared that it was 901 compatible.

However, when I try to put the atomizer into the device, it's too large to actually go into the hole and screw in.

I guess I need to get myself a 510 or an 801?

EDIT: Got my question answered. I need a 501-901 adapter.

I suspect you may find the 901 a bit weak on 3.7. I have a bart too but mostly use higher volts devices. If I use 901s on Bartleby, I only use LR 901s as I find the native 901s to be around 3.3 ohms and work best in the 4.7 to 5.0 volts range. Hope this helps you.
