I am super impressed with this light. The quality and features are really impressive for $30 USD. The emitter options are great, and although I was apprehensive about the TIR lens it works well in this light to give the beam a bit more "oomph". The 2700k 519a is a gorgeous tint - that alone makes this light worth buying. But you also get fun body colors (ORANGE!!!), some nice aux LEDs in both the head and switch, and a very pleasant form factor which feels great in the hand while still being extremely pocketable. This one is absolutely going into my EDC rotation.
Others are saying the UI is terrible. I disagree. The UI is *different*, but in my opinion very well done. If you want the UI to be the same on all your other lights, don't buy this one. If you are willing to learn a (very simple and intuitive) new UI, give this light a chance! Honestly I don't understand why people are hating on the UI so much - I kind of like it. But to each their own.
Fireflylite, great job on this one - It's a real winner! Also, please offer more lights with this orange color :D
