what came first the DSE901 or the RN4075?


Recommended Posts

Got a question for my experts on the site here.

I ordered a DSE-901 stainless w/pink led from one supplier then,

I ordered 2 batteries and 2 atomizers from another supplier cuz his parts prices were good.

Got my kit then I just got my batteries and they are 1-2 mm shorter and have a code punched into the interior where threads are that say SLB and some numbers (serial?). I am thinking that these batteries are true 901 batteries from Sailebao (SLB)? and the starter kit I got was an RN-4075. Okay right now you are thinking "who cares?" but I am wondering as I hear comments about "knockoff" parts and I would like to know what came first the chicken or the egg (the DSE901 or the RN4075)?

Anyone have thoughts on this? Please advise.

I think Ruyan actally came first and they came later.

From what I'm starting to learn, DSE actually is better than RN. I just got some new Pensyle batteries (woot!) that are working great, I think they are the DSE model.

As for who came first DSE or RN who knows

Actually that is what I was thinking too. I have seen other sites with lengthy descriptions of what seems to perform best and it is the DSE models over the RN models but basically I understand the RN are actually the first Ruyan models.

So I am thinking I will keep ordering these parts from this guy cuz I got SLB which seems to be the better product. For my 901 his batteries are $11.99 and his atomizers for the 901 are $7.99 and by the way they too are stamped with SLB.

Ordered 4/26 received 4/29 from Maryland. Not bad.

actually i DO like the DSE901/RN4075 BUT where they are said to be the same they really are somewhat different

Same ecig - different manufacturers with minor nuances and nuisances.

RN4075 Ruyan

DSE901 Sailebao

4075 battery is 69 mm and fits both style atomizers

901 battery is 66 mm and fits both style atomizers

4075 mouthpiece & cart are 2 separate pieces

901 mouthpiece and cart are 1 piece

4075 mouthpiece doesn't fit 901 atomizer - it's too loose

901 mouthpiece doesn't fit 4075 atomizer - it's too thick

4075 atomizer mesh is lower and wider

901 atomizer mesh is higher and pointier

~~~~~~~~~~~~~~~~

supplies on hand:

1-4075 atomizer

15-4075 carts

2-901 atomizers

2-901 carts/mouthpiece (need more of these)

SOOoooooooo, my point is finding the proper parts will be interesting cuz everyone says they have the 901 when in fact it may or may not be a 901 or 4075. So I really must see an image of cart/mouthpiece

esto me sorprendióI discovered all this cuz I purchased a 901 Starter Kit from one supplier, I purchased 901 parts from another supplier. I do believe the kit is a 4075 and the additional parts are true 901s.

As I continue my research re: performance I will let you know my thoughts.
