The things you hear about restricted airflow are most definitely true, however, that is at the expense of by far the smoothest rip I have ever received from the bong. The coil must be cleaned out every 1-3 days or it WILL clog, however this can be as simple as blowing water/alcohol through the top end.
I had two of these and sadly both of them broke but the bottom pieces are perfectly fine just the two top pieces on both of them broke and there’s no replacements anywhere
Now I’m just sitting her with two bongs that don’t freeze and don’t work. Very upset ):
