Before the push button/ clicky tailcap modification that Zodiac Engineering did on my 4Sevens Preon 1, I was searching for a better clicky tailcap mechanism for a AAA light. I was frustrated by the OEM clicky tailcap on the 4Sevens Preon 1, but I read on some forums that it was possible to remove the glued-on Streamlight Microstream head and use it’s body with the 4Sevens Preon head(with a much better interface). I received my Streamlight Microstream about a week ago and immediately started carrying it to get a feel for the push button. I have to say that I’m not impressed. My biggest complaint is how difficult the button is to depress. On my light, it starts out with the same required pressure as the 4Sevens Preon, but as you reach the bottom where the switch will click, it requires more and more pressure.
Yes, the extra pressure makes it less likely to be turned on in your pocket, but when you are frequently using the light, it makes life miserable for the user. I’ll continue carrying it for a little longer to see if it grows on me, but as of right now, I’m ready to head back to the 4Sevens Preon 1 with the push button/ clicky tailcap modified by Zodiac Engineering.
Here are some photos comparing the 2 lights:
