Beware , the ML300 is of poor quality, and incredibly poor after-sales support.  One of the RED (visible) LED is faulty, and seller is has been deceitful , manipulative and evasive - refusing to accept liability and responsibility that it's faulty ,  claiming that they had updated their LED document  (which they had originally sent me on 18th March) which shows that the faulty LED is actually NIR/invisible, yet they are unable to produce this "updated" document to me !  I have not even tested the invisible/NIR LEDs yet will be using special equipment for those.  Either way I have no confidence in their products.  Additionally, the  goggles they sent me were faulty - the spring/plastic  mechanism is internally broken , and they had a audacity to ask me to "fix" something which cannot be fixed !  I totally regret buying from them. Never again and steer clear  from this company.
