I have the 50w Istick and a Lemo Drop on it. Yeah, I'm an Eleaf fan now. I vape between 20 and 30 watts with a 1.2 ohm coil. It's great. When I throw my full size Nautilus on, I have to drop the wattage down to twelve watts, or so, to avoid a burnt taste. The 50w will give you more flexability for your builds. One device fits all kind of scenario. It will fire down to .2 ohms. Of the three devices that I have, it is by far my favorite. Compact, comfortable to hold, sturdy, two 18650 batteries w/usb charging. If you get into sub ohm
vaping, you can really take advantage of the power. Or, like others have said, the battery power alone is a great plus, along with the small form factor. Also, it's 23mm "deck" means that your
tanks won't have any overhang. Picked mine up for $48.00. I don't regret it at all.
