DeltaPrintr's Mini Hotend
A critical part of any FFF/FDM-based 3D printer is its hotend. Deltaprintr will soon be releasing an all-new "Mini Hotend" which will provide some big benefits in a size up to 50% smaller than available hotends. Once available, the hotend will be priced around $20-30 and will be mounted using two screws--making it usable on virtually any FFF/FDM 3D printer. The Mini Hotend will feature a powerful tiny fan in it, allowing for the printing of materials that require high extrusion temperatures--it can reach up to 700°C (1292°F).

So what's the point to reach 700degrees C? What plastic can withstand that temperature, without burning, or carbonizing?
Are they sure it's even close to 700C, heck, even engineers are known to screw up big time on occasion. It's not the first time we see this kind of bullshit lying around. What sensor are they using? THermocouples, thermistor? Used a 3rd party device sensor?
and...
"Stainless steel construction – one single piece from top to bottom of nozzle, meaning no more clogs"
Fail
Never ever use stainless steel for this kind of application.

As a metal alloy, it belongs to the worse category for having piss poor thermal conductivity.
The heat fins is one of the reason why it will have trouble to cooldown.
