The New 901 (2009 model)
I received the new 2009 model of the DSE901 from Patrick at the healthysmokeshop.com last week. The selling point for this model is extended battery life and improved vapor production over previous models. My main e-cig of choice has been an 801 (penstyle) but I was looking for something a little more compact and the m401 models don't appeal to me because of the cartridge design.
From the outside, it looks like any other 901 model, though it is a couple mm's shorter. The fit and finish is very good; it has a nice sturdy glossy black paint job. Upon taking down the 901, the first thing I noticed was that there are no model markings on the battery connector nor any other part of the 901 for that matter. The "wicking bridge" inside the atomizer rises higher than previous models which dips deeper in to the cartridge to grab more juice. The cartridge design has also been changed, however, older 901 cartridges DO fit with no issues.
Another big change is the switch in the battery. Previous models used a pressure switch whereas the new 901 now has a sound activated mic switch like the m401. I'm not sure how I feel about this yet. Loud music, wind, or any bump to the 901 will activate it; including the removal of the cartridge. Luckily, there is a 7 second cut off that will prevent you from burning out the atomizer. On the plus side, it makes drawing easier and more like that of an analog cigarette. I've been through enough batteries to know that the pressure switches usually gives out before the battery does. Hopefully, the mic switch will address this. As an experiment, I removed the LED cap on the battery and put a couple drops of hot glue in the 2 draw holes on it. This made the mic switch less finicky and has no adverse affect on it's performance.
But hows does it perform you ask? Well, I am quite pleased. In the beginning, it was producing massive amounts of vapor, but very little throat kick. I find this pretty standard with any new atomizer. After a day or so of vaping, the throat kick started. Now, a week later, the vapor production is still as good as it was from day 1. The amount of vapor it produces is on par with my DSE801. While that doesn't sound like much of an improvement, I should add that my 801 is hooked up to a 5volt battery that I made. When compared to the 801 with a regular battery, the new 901 blows it out of the water. The battery life has also improved. I am one of those people who finds themselves constantly vaping all day long. So naturally, I wouldn't expect to get the 12 hr battery life that is claimed for this product, however, I do get between 6 -8 hours on it. If you used this product like an analog cigarette, I could easily see it going for 12 hours on one battery. As with all previous batteries, the same rules apply - charge it for 8 hours before first use and 4 hours there after. Another thing I noticed is that way the battery works. You get nice full draws all the to the point that it dies. While this is nice, the downfall is that you have no way of knowing when the battery is reaching the end of it's charge. It also only flashes about 7 times to inform you of it's depletion (unlike the usual 20-30 times on other models).
A couple things to note:
As stated before, the mic switch on the battery is finicky but can be remedied easily. One other thing to note is that the 901 is very juice hungry. The atomizer seems to heat up faster than previous models so you will need to keep it a little wetter than you're used to. Whenever I refill my carts, I also throw another drop or two on the atomizer itself. I also find that stuffing my atomizers with tissue/toilet paper every other night to drain them keeps them fresh and adds life. I still have a penstyle atomizer that is 2 months old and still draws like it did when it was new. I've been doing the same with this 901 atomizer and all is well. The last thing to note is that in one of my previous posts, I stated that the battery threads were different than other 901's - this was incorrect. All parts on this model (including the battery) are interchangeable with other 901 models.
I hope this was helpful for anyone looking into buying one of these and feel free to post any questions you might have!
