Just had my first stem with my new Underdog. All I can say is WOW. The performance, look, and feel of this guy is top notch. I've a MyrtleZap and RockZap as well so I'll compare them with the Underdog.
Performance: Easily got 5+ hits on my first go and the clouds were always top notch. I got two wispy hits at the end and then sensed "the taste". I blew out the ABV and it was a dark brown, just how I like it.
I must say the
airflow is unbelievable. One of my biggest complaints of the MZ is it feels too much like a thick milkshake when drawing. The RZ has a much better flow than the MZ, and the Underdog is superior to both.
Easily my favorite aspect of this vape. As for efficiency, its in the running for best at that too. I need to do proper analysis to determine which is better at conservation, but I doubt the results would matter very much. Log vapes are awesomely efficient and the Underdog is no different. I just filled the stem a quarter of the way and produced 7 visible hits. The silicone is certainly different than the nylon and wood stems of the Zaps, and I think its great as well. The mouthpiece will forever be a subjective category as everyone has different tastes, and I enjoy the silicone. I'd love to give a glass mouthpiece a try as well. The silicone fitting around the heatport is a great idea and everyone likes glass. The combination of the two seems like a perfect combo. But I digress.
Look: This is a Birthday Dog so its made of simple ash (if I'm not mistaken). It looks like its composed of 3 different pieces. That with the scooped bowl thing its got going on at the heatport, makes for a good look. The grains show up well and the light color of the wood is pleasing to the eye. The finish makes her shine
I would say my RZ looks better (finger grooves, dyed blue and green, you understand), but that's not to say Dave doesn't make some gorgeous vapes (Absymal's for example). This is a birthday vape so it was understood they'd be simple. Simple and elegant.
I will say the Underdog is better looking than my MZ though. The grains don't please me, but it does have an LED, something I'd love to see in an Underdog.
Feel: Big and round. Perfect fit for my hands. I've got some good hands and like to get a good grip on things. I was worried I was going to get that teeny one in the front row of the pic. I like to have a big hunk of wood to hold on to. The Underdog has a greater diameter than either Zap, but it is shorter by an inch and a half (MZ) / half inch (RZ). The height is fine though and fits my hand well. The RZ's finger grooves makes it the best to hold, and the Underdog is 2nd. MZ 3rd.
Overall, extremely pleased. I'm afraid my beloved MyrtleZap shall forever be an aromatherapy diffuser only now. The Underdog and RockZap are just too good. I'm not going to place one above the other because I don't want to do a disservice to either. Both are excellent vapes and I recommend them to everybody. I'm very happy with the Underdog and I hope to get a 3/8 core in the future.
