Never said it was an unnecessary feature, just stated it was not in high demand and the only device I’ve seen employ said feature was a DNA. The 10 second cut off found on the majority of devices is there to mitigate damage from accidently firing the device. It is not there to modulate ones intake.
According to Joytech, the Primo states “ For safety concerns, if you hold the fire button over a certain time, the device will shut down automatically… you're allowed to set the timeout duration from 5 to 10 seconds”. I guess that can be used to modulate ones intake, assuming your puff duration is between 5 and 10 seconds (what if you prefer a 4 second or lower puff?). But that documentation indicates to me that the feature was implemented to mitigate damage from accidental firing, not modulate ones intake.
Joytech, Wismec and Eleaf are all under the same parent company so naturally they will share features, just as they share the same microprocessor controller. Current Wismec devices that employ this adjustability enter a stand by mode should the 5, 10 or 15 second pre-set times be exceeded. Again, this indicates to me a feature to mitigate damage from accidental firing. Why would a device automatically enter standby, thus forcing a user to 3 or 5 clicks out of standby in order to vape, if the feature was meant to control ones intake?
You are welcome to ask for such a feature from Vaporesso, but I think @UncleEddy response is just logical.
