I have had my Dog for about 2 months now and it is the best vaporizer I have used, surpassing the Arizer Extreme and even the Vapexhale Cloud among other lesser vaporizers. In addition to a solid product, the customer service has been top notch. When I first received the unit, it was running rather hot and charring bowls so I contacted Dave and he immediately sent one of the new switch mode power supplies that supposedly runs at a lower voltage and lo-and-behold my problem was fixed (although it still seems to run slightly hotter than average, and I have to cut the silicone tubing a little longer to compensate). I went to order some accessories a month later and the post office seemingly lost them, so they sent another shipment and all was well. I really enjoy the personalized touch, and have enjoyed my correspondence with both Dave and Amanda.
The only con I can even think of is that I wish the silicone could have been replaced by glass or something because it needs to be replaced occasionally, and bud tends to stick to it. Also maybe a temperature dial built-in, but that is more of a design choice due to the external power supply.
I chose the Underdog to replace the Cloud after being unimpressed by its performance and experiencing poor customer service from Vapexhale. Devices like the Extreme and Cloud are quite easy to use, but the Underdog still has them beat by running at an ideal temperature… you just plug it in, pack a bowl, and go for it. As you hit the bowl, despite the constant thermal output from the Dog, it will slowly increase in temperature and give different types of cannabinoids as the buds transition from green to brown just as you would expect by increasing the temperature on other vaporizers. I attribute this property to the highly restricted airflow. The restricted airflow also seems to make for a very smooth (not harsh), potent, and tasty vapor experience. The taste is exactly what I expected to get out of the Cloud but never did, and the potency of hits is substantial especially using concentrates. I found that, like the Cloud, stirring is unnecessary but if you do it then performance will improve on the last few hits of a bowl.
I really enjoy the versatility of the Underdog also, in that I am able to use it with various glass pieces using the excellent wood-on-glass attachment. I was disappointed with the fragility of the Cloud, and I am simply in love with the indestructability of the Underdog combined with the wood-on-glass bowl which is very unlikely to break. Another form of versatility is the wide range of concentrates that can be used with the bowl pieces – with previous vaporizers I had difficulty either with packing concentrates, having them make a giant mess, or having them go to waste due to poor airflow. Packing concentrates is extremely easy using the “sandwich method” and the airflow is great as long as you don’t pack the bowl too densely. Cleanup couldn’t be easier – usually I can reuse a wax bowl once just by cleaning it out with the included pokey tools, and then after the second use I just pop the screen out and put a new one in and it’s good to go again. I just slowly collect the dirty screens and then wash them all at once. The Underdog is pleasant to hold, like a gentle hand warmer although it gets pretty toasty at the very top; this is in stark contrast to the Cloud which reached scalding temperatures and required insulation to hold. Finally, I enjoy being able to leave the device on 24/7 if I want to because it is very convenient to just have it ready to go instead of waiting 5-10 minutes for a vaporizer to heat up. Overall, I am highly impressed by the Underdog and there is very little room for improvement. 9/10.
