Never was bitten to the big guys, the tinsel, or the jewels. However, just added my plug on “Flashlights that are great but you hate them” was the S42. Bad UI that I changed with Lexel’s driver. All in all, some $103 CDN spent; this was my first light.
Learnt a valuable lesson - better have a good UI, a bad led can be reflowed for cheaper. Bad driver (looking at you Sofirn w/ timed stepdown) is also a no-go.

Limited $$$ as I would scrap the driver on my FT03 w/ SBT90. $122 on a light that misbehaves in turbo. I’d expect it to gradually drop down and not bounce up and down. There’s a short within the driver and the LED stays dimly lit. Astrolux prepared to sent over new driver but waiting for the Corona Virus slowdown to subside, perhaps Mateminco will correct the instability on next batch (but I’m not holding my breath).
