I do not know if you have official sales points for IMALENT in your country - we have a couple of them here in Germany. Because at the end the problem stated her is just based on one single point:
You get what you pay for. Period.
- Possibility number one: you buy the flashlight for the full price in your country - here in Germany it’s around 400,- US$. In this case you get the a receipt, the full service and everything is fine.
- Possibility number two: you buy it in China - and you just pay about 220,- US$. In this case you know in the beginnnig that there might be trouble - but you saved a whole lot of money
So, based on this, it always places a smile on my face when somebody expects the lowest price with the biggest service…
And if somebody asks: yes, I have a lot of IMALENT - and we really use them, means they not stay on the shelf but they have to work for the energy they consume. Based on this we just had one minor fail with a DN70 (sometimes she gets off when you directly go into Turbo) and one contact with Shellen (wtb a new tube for a DT70, the one with springs, worked flawless).
Based on the discussion here I even tested all three DX80 we actually use, none of them with the described error - my burning eyes can testify…
