I can’t think of anything negative to say about the EC4GTS when it comes to fit and finish ( build quality ) , it is simply superb . Now there is a little bug bear ! The EC4GTS does not utilize flat top batteries ( yes I tried ) . Most of your high performance 18650 are flat top . I do not personally wish to use re-manufactured 18650 and very much prefer the factory stock unprotected high performance 18650 as they are ( For my own reasons ) . I would really have loved to have thrown in some of my 3500mAh LG , but even with two older button top 18650 that would have been middle of the road performance wise say 5 years ago the EC4GTS performed really well . ( Actually I never thought it would do as well as it did with these older batteries ) .
My apologies to Nitecore , because I am still suffering from the flu ( into my 2nd week ) and as I write this nausea is affecting me and it’s really hard to concentrate . There are so many more great things to talk about , please take the time to visit the product page and check out the EC4GTS because I really feel the need for a lie-down .
I like everything about the EC4GTS , the tailcap ( yes I like it ) and the way the Rubber seals have been done . I really like the two button system , the lock out , lack of battery slop , size , the emitter , seriously !!! The only thing and it is just one thing ! The EC4GTS does not utilize flat tops …… This is for all purposes a 10 out of 10 light , but I am docking half a point for not supporting flat tops .
