510 vs. 901: Just what IS the difference?!

[Katatawnic]

I'm currently a Joye 510 user. Looking at the Riva now, whose battery life is appealing... I'm tired of switching batteries every hour! I remember reading somewhere that problems with a leaky 510 cartridge can often be rectified by using a 901 cartridge (makes for a slightly tighter fit), so that would indicate to me that 510 & 901 must be fairly close in design. (?)

What is the difference between 510 & 901 PVs? I know this info has got to be around here somewhere, but I searched half the morning away, and haven't found comparison posts/threads.

I'm under the impression that 901 atomizers don't get as hot as the 510s do... not sure if that is correct though. All I know is that for $30, it's well worth it for me to try one of these Riva kits... but I'm completely undecided as to which I should get.

So today's question is... stick with 510s or switch to 901s? Can I get some pros/cons for these, to help me figure out which would be a better choice for me?

Thanks in advance.

(These are the URLs for the Riva starter kits @ $30: 510 901. If price is not set to $29.99, use discount code "august20" which is good through October.)

901's do seem to run a little cooler. I personally like them. I started out with the 510. I still use 510 attys, lr 510 attys. But I now also use 901 and lr 901. The lr 901 is my fav. I would suggest to you to get an adapter and try out a 901. For the riva i would suggest the long adapter, not the short SS (stainless steel) one. I found the 901 performs better without the cone. So if you like the cone get the long adapter (coupler).

Nice prices on attys here

Thank you, Bert. Not bad prices at all.

I have no idea what the cones are for, only that everyone says they are optional. What interested me about the Riva PVs was the longer battery life. So I figured if I'm going to get a whole new starter kit, perhaps first I should find out what the 901s are. Plus, a couple hours ago, I saw that their 510s are sold out ATM, whereas they still have 3 of the 4 901s (i.e., color choices) offered. I'm not surprised they've sold so much at this price; I just don't know when they'll be restocking.

A cooler atty means less harsh, correct?

Also, what do LR attys accomplish?
