I bought a cheap vape on eBay, cheaper than the one you posted a link to. Once I dialed in the temp, I can leave that thing on for hours and it's still perfect temp. It's not high tech, and doesn't fill bags with vapor that you can sit and puff on, but it does the trick just fine. "Whip" style vapes have been around for a long time, and the technology isn't exactly what I would call advanced. That being said, I found my 28 dollar whip style vape to be solidly built, work very well, and be a great value. Glad I didn't spend more than 28 bucks on it, cause much like racerboy, I VASTLY prefer a combusted high.
