Hi Meef. I couldn't say how good it is? I am a newbie. I don't have a clue. I am very technically minded and know good quality production when I see it. Well my Kind LED L450 K3 had accumulated a lot of dust inside so I decided to take it apart for a clean. It did not strike me as a high quality piece of equipment. I was scared of cross threading the screws they are your typical cheaply made chinese and the metal is all low grade and doesn't look / feel good either. I have hi-fi equipment that is just amazing high quality materials. It's only an LED so can't be that expensive to make. I really love my light and I am so happy with the results. I think there is a lot of hype. Some people say this light is exactly the same as the Apollo 8. I don't know what to think? I know one thing it is cheaply manufactured and to me that means I'd be careful as I think there is too much hype. As for durability only time will tell.
I hope not to put you off as it may well be a fantastic light but do your research.
