using the analog version of this for ages... still going strong. but when i had to buy an iron today i would go for an iron that uses t12 hakko tips. integrated heating element in the tip is just superior and there are good stations with oled display for about 50€ bucks on banggood or aliexpress.
Any validity this video would have had, was lost when you called the LED screen an LCD screen, then you called BRASS copper, then once again you called the LED screen an LCD screen. I stopped the video at that point because you OBVIOUSLY don't have any idea what you are talking about! Also, the temperature is in Celsius, so it showing 251 would be around 483 F. Also, you don't measure temperature with a THERMOSTAT, you measure it with a THERMOMETER! Learn the PROPER names for things BEFORE you make a video!!
