1. One hit-extraction.
I have found recently my Grasshopper to be my preferred choice for one hit extraction through my bubbler. I like to load about 0.05 in the chamber and hit this through water on maximum heat level. The good thing is, that I don't have to stir, it extracts really fine, one huge cloud, dark coffe-brown ABV.
=> Can this also be done with the Evo? I am chasing high temperature / micro dose hits and having to stir to fully extract a little amount of like 0.05 - 0.1 g would be a no-go.
Yes, EVO is totally capable of efficiently one-hitting micro-loads. With large lung capacity, you could one-hit even a bigger bowl (but that's a killer cough).
2. Turning the unit upside down.
Is it really recommended to NOT use the EVO inverted?? I can remember reading in an interview with the CEO of the company, that this would be one of the features of the EVO, being able to use it with any water pipe I already have. And I have plenty, so have there been made some changes regarding this behavior or is it still okay to use the EVO upside down for quick hits ?
No, they've just worded the caution a bit wrong. It's already fixed on their site. It just should be LEFT inverted for EXTENDED PERIOD OF TIME. If you want to hit it inverted through your own glass, do it. Just don't leave it there...
Leaving it there could make the heat slowly raise up and heat the electronics, which they don't like.
Also you would be at risk, that something woulnd knock it over and break your EVO. This also count for hydratubes.
It recently happened to me: I had an EVO with a hydratube, I left it for a minute unattended and a gymball in my room somehow started moving, gained momentum and knocked my EVO over, the connected hydratube broke the joint on the EVO and it's now in repair. So, don't leve the EVO connected to any glass unattended.
3. I had the chance of holding an EVO in my hands some months ago. The EVO had this neoprene sleeve on and the velcro fastener on the bottom of the unit was covering the air-intake hole. I didn't want to ask, but I am sure this must had been an user-error and not meant to be like this, correct?
Did the velcro reallyblock the airflow? I doubt it, its not a rubber plug, and the most restriction the air has to go through are the holes in the bamboo glass. Any "leaks" through that velcro strap are going to have less restriction than that, so so wouldn't notice. Also I noticed that having the velcro cover the intake helps reducing the whistling that EVO makes when you pull at certain speeds. So, the velcro over the intake is not a problem.
