You know what, i think i'll do better than that!
I have ordered a 510 to try it out and see what the fuss is all about. It seems that this model is smoking the Mseries literally. But all i've heard are comparisons between a manual switch and the auto Mseries. Thats hardly a fair comparison.
So why don't you guys help me out on what i should recommend to Smoore for improvements? So far, i've got the following:
1) Cartridge to hold more liquid
2) Cartridge to be refilled easier
3) USB passthrough and manual switches. (Please explain to me why the USB PT needs to have a manual switch?)
4) Perhaps a not so sensitive battery? - But i wouldn't wanna sacrifice any of the current performance.
I also have concerns with the above recommendation. Currently, the design of the ecig is rather cool and sleek. If they were to really incorporate the cartridge design of either 510 or DSE901, it would make the atomiser longer and imo, less attractive. Is that something we can all live with?
I'll compile something more detailed and submit it to Smoore via AEC, as they would most likely be able to translate it to Chinese for their engineers. Please only provide constructive suggestions and not waste time flaming one another, as these can sometimes happen in topics like this. Thanks a bunch, guys....
Haha... I see we both broke down

... anyways, i agree on all point EXCEPT the last one. I feel that if we are going to have an automatic battery, it needs to be as sensitive as possible (well not so much that any little thing will set it off, but...). Other than overall poor performance, my MAIN gripe with the eHealth model was the fact that i had to give my lungs a workout just to activate the battery. If it activated like a M, then i "could" have lived with it, I wouldn't be a happy camper, but i could live with it. An easy way of improving the carts, is simply to bring back the old "peg" style carts. Do you have any clue why they switched styles? It seems to me the peg had the lightest draw, and held a little more liquid than the wing design. They are more fragile, but the preformance was well worth it.
Also the many people searching for a less sensitive battery are mostly looking because of clubbing, live shows...ect. If Smoore released a manual batt, this could take care of most of thier needs. Don't get me wrong, I love the mic switches in the auto batteries when I'm driving, or other times when i don't want to "think" about vaping, but for most other situations or when i need my nic fix the manual provides a better overall experience.
In terms of size, this is indeed a double edged sword. When first starting out vaping, many of us want an analog replacement. Size matters. However once I started getting used to the fact that i was now a "non-smoker" penstyles and mods did not seem all that unattractive, especially for the performance it proves. Many on this forum relate the M401 to a sport compact car... relatively cheap, easy to maintain, good (but not Italian sportscar) performance, EXCELLENT gas mileage (both battery and juice) all in a nice package. For me changing the M would be someting that i would TOTALLY be interested in, however I'm not sure its something that NEEDs changing.
Constructive critisim is very welcome an encouraged!
