I bought it, used it for a while, and am returning it. That makes it sounds bad when it really isn't, but it doesn't fit my needs.
Pros: build quality is excellent, and I mean really excellent. Everything is perfectly fit together and perfectly clean (or lubed). And I love the styling. Also, the light is designed so that many aspects can be decided by the user. eg, lanyard, grip ring on/off and position, clip, and you can even unscrew a rear retaining ring to make the switch protrude without affecting waterproofing. However, this does lead to the largest number of major parts I've ever seen in a flashlight.
Cons: Switch flickers when turning on for the first time - issue with circuitry, not switch. And the UI in general could be a lot better, and definitely more reliable. And, of course, it isn't very bright.
I've owned a Tiablo A9, MA6, and A7, and each one represents a huge leap forward. But I don't think Tiablo is on top yet.
