While some may complain about complicated UI's, I say why aren't there MORE torches with fancy UI's?
The market is flooded with simple on/off flashlights. Go visit Target, Walmart, your grocery store, simple flashlights are everywhere. That's why I come to CPF, to seek out more advanced flashlights that offer more than your average off the shelf flashlight.
There are plenty of options for those who want a simple flashlight. So now we have people complaining that some companies dare make a flashlight with a "complicated" UI? So no one should make a flashlight with an advanced UI, because if they do, someone will complain about it?
"Why are torch interfaces so complicated?" last I checked the majority of torches on the market are simple ON/OFF, and the minority, the niche market of flashlights, have "complicated" interfaces.
If you want off and on with a dial, try a Surefire U2. To say ALL flashlights made should have the same on/off with a dial is ridiculous. The more flavors the better.
