Preflash on the lower settings bothers me to no end so I can understand your dissatisfaction. I own many 4sevens lights but not a turbo or tactical. Perhaps you could try a regular quark or if you can afford it a g5. The g5 does have a delay when pressing the tail cap but it's only on medium and so i have no difficulties or gripes. All other modes work great. If its too large I highly recommend the nitecore ife1. I haven't had any problems with delays or pre flash. I'm sure although 4sevens has an explanation for the pre flash I'm sure they tried and possibly are trying their best to eliminate it. Prehaps not in the current generation due to the large cost of engineering. But perhaps in it's successive generation. All companies if they want to remain successful evolve. I'm sure 4sevens is in it for the long haul and are spending what they can to engineer great lights while trying to remain profitable. David's been great to us here and so has alot of other flashlight companies. I think we should all voice our opinions so they know what needs to be fixed but I don't think we should write them off unless there has been some kind of egregious errors or comments from the company itself or it's representative.
i won't write them off, i know that they are a very young company and they do things i do like: moonlight mode, beautiful aesthetics (some of the best looking lights ever imo, clean and knurled all over) and nice options like warm/neutral etc but i'm just not ready to buy one yet and until i can get one for a reasonable price in the u.k. they are out of my reach.
next week i will probably feel differently, last month i really wanted one, i want a aa2 and an aa turbo but not with preflash and not yet
i like the turbo but don't like the tactical interface, am i right in thinking that on a regular quark you have maximum output when fully tightened and moonlight when it's loosened?
i do like forward clickies though
