Price is cheap, and this one appears to be the most commonly offered one on Ebay.
Why do you find hot air more effective? I find that if I have to poke at component pads then you might as well melt the solder in the process. Also, solder paste storage and expiration.
There's nothing wrong with warning someone that a new piece of equipment might not solve all their ails. I could argue you're misrepresenting things when you say small components stick to the iron since you're obviously not holding them down with tweezers if that's the case. Very similar to if I claimed that with hot air you risk blowing away components when you could just respond by saying that excess airflow is being used.Apply solder paste. Put the part down aligned as well as possible. Apply heat and the part magically pops into perfect alignment because of surface tension. Couldn't be easier.
Resistors and other small parts....heat them with an iron and they stick to the iron.
This works for me. It may not for you but don't make a pronouncement based on your experience that will hold others nack from trying.
