Tell me about a "901" ??

The 901 is good but I actually think the 510 with manual switch is better. So, IMO, stick with what you got.

 

The name is DSE 901
It's a 3 parts cig with a tube type vaporizer like the 510
Yes
Bestecig or Eastmall maybe

I have both. I think the 510 produces more vapor and most liquids have more body and flavor when I vape it in the 510, but most have a stronger throat hit in the 901. There is no PCC for the 901. The batterie performance is equally bad on both models. If you are looking for outstanding battery performance, take a M401.

The vaporizers of most 901s are pretty good, and if you like dripping, this is your choice.
Don't drip the 510 if it's on the automatic battry!
The 901 is probably the most popular steamer worldwide.

I currently use a 510 cylon in stainless steel with manual batt and love it
very easy to clean the vaporizers,great throat hit,great vapor
My friend tells me that the DSE901 is better so mine is on the way
he also uses a 510 yeti

 

There are NO advantages to the 901 over the 510 or any manual PV. Don't waste your money. From where you have started with the 510, your next progression would be to the Prodigy, Protege, Screwdriver, GG or Janty Stick.

 

What???? Does an M401 get 7-8 hours of battery life from heavy vaping??? I don't think so. Using the words "outstanding" and "battery" with an M401 will be quite misleading for new vapers.

 

I will always have a "soft spot" for the 901. It was my first PV and got me off the analogs.............

Fortunately I have matured and progressed in my vaping experience and the 901 is only a distant (but fond) memory.............

 

I think you have a good, better, best scenerio here.

The 401 was the best "mini" e-cig for awhile. A lot of users still like it for the flavor it produces. Known for battery life (3-4 hrs).

The 901 may still be the best "all-around" mini e-cig because of vapor production/throat hit and flavor. Not known for battery life. (2-3hrs).

The 510 is known for the most vapor production and "throat hit" for a "mini" type e-cig. Not known for flavor reproduction or battery life. (1.5 -3hrs).

Then it all depends on how you use the e-cig. Your mileage will vary.
