I do not know a lot about Heatbit. They cost $1200, right? And you cannot change your mining pool, it uses Nicehash, right? You can buy a used S9 for $150 and have 100% full control. How loud is your Heatbit at 14TH/s? My S9's are underclocked at 10Th/s and aren't loud at all. The nice thing about Heatbit is that it looks great, like you said. S9's are "ugly" unless you get a nice 3D printed case for it.

How much are your underclocked S9’s generating for you #[3] ? 👀
It's not a whole lot, about 20K per day on average.
Have you guys seen what #[5] has been doing with their s9 heater setups and data collection? 
Yes! This is actually one of my favorite threads on Twitter.
This heatbit company is shit. I paid 1200 for a heatbit and it is a paper weight now. Stopped working after 2 months. Customer service just strimgs me along with excuses and its been over a month and i havent got a replacement. I finally initiated a charge back on my credit card.
If you want to see the email copies i can show you i saved them all.
