Hi jokiin, i am glad that you are currently being online, so may i ask: How come my brand new dod ls400w plus has a very annoying issue that when temperature is little high that it loses focus??? So after i buy i had to returned to the seller and got another new one, but it is same! Now when i am writting in here my ls400w plus has been sent to shenzhen official factory to test it out, and been a week+ already, their support told me this afternoon that they have done 75c degrees testing and found the pictures are blurred, now they are doing 45c degrees testing again. I am very disappointed because i do not think they will fix it anyway, but would you suggest me a mode of DOD that it may have better heat-defending so that i can question them to replace it for me please? because i have asked them to fix it to me and while they are doing the test they have forwarded my message to their Superiors. Thank you.
