Institutional knowledge takes years to replace.
I don't know of any with swappable batteries anymore. The HTC U24 and U23 series both have headphone jack and MicroSD slot. There are a few others.
The Oppo X8 (non-Pro) is probably the smallest flagship with a top level chip and good camera currently made but it is only available in a few markets.
The situation regarding Dejoy is not so simple.
True, their electric grinders are very stylish.
Unless you are attaching your hand grinder to an electric drill, a person cannot apply enough force or speed to generate the high RPMs to generate heat. You are way off base on this.
Never buy a ceramic burr grinder these days. I've not used this specific one but for the money it is a terrible choice. These days there are fantastic high quality steel burr grinders available at a similar price from Timemore and Kingrind or other lesser known companies. Well made stainless steel burr grinders are faster and provide a much more consistent grind size/grind variability than ceramic grinders.
If someone is buying a new grinder they should stay away from Porlex ceramic and Hario ceramic burr grinders. 20 years there were no other choices at those prices now there are tons of far better grinders with stainless steel burrs. Porlex is overpriced garbage.
OP is a douche
Nice coffee corner. What grinder is that? Consider that other than the beans, the quality of the grinder has arguably the greatest impact on the quality of the cup of coffee. An excellent grinder can improve every form of brewing.
The Vietnamese brewer is called a Phin. You can likely find them at the local Asian market and always Amazon.
Traitorous sack of crap gonna do traitorous sack of crap things.
