First impression: It's nice, I really like the new switch that Sofirn used here. It's like the large switch from Wurkkos, just smaller and far better than the hard, wobbly switch they used in the past.
The tint is mediocre and the Fresnel lens creates some rings. Unfortunately also some tint variation from spot to spill. Overall pretty soft beam, but not too floody.
It appears like the bezel is press fit, but it has a small gap and it might be possible to open it.
Interesting place to attach the clip. There's this large groove at the front. Looks little weird without a clip, though.
A magnet is included as well, but it can only be used when no lanyard is attached (D'oh!).
I will write a full review, but it will take some weeks because I have quite a lot other flashlights in the queue.
I had the Slimblade for five minutes, until I quickly returned it because of the bad buttons and the high ball without a proper wrist rest. Eventually I found the Elecom Huge which was just perfect for my hands. The Deft Pro works also great. Tried various other trackballs including thumb trackballs, but none worked as good as the Huge for me.
