I have a atmos pen vaper. Actually works quite well. My biggest problem is the same thing you have with any product. The more you use it, the more it reeks. I've kept this pen quite clean and it came with a spare heating chamber that I have not used. It's a little hard to clean, just due to the way it's made. The odor after multiple uses cannot be hid unless it's in an airtight container. I will admit it's great for complete burn of the weed and eliminates the waste you might fine with a pipe. The only issue I have is that it's good for a quick one hitter and quite effective, however, once you fill the chamber for multiple hits, you have to take the top off and stir the product to get it to the bottom near the element or it doesn't burn properly. And when you do that it's hard to hide the scent and keep it off of your hands. Not bad for normal situations but clearly isn't the best idea for stealth if you need it.
