So my brand new mkiii 2aa quark arrived today. I’m sad to say I already have email communication with customer service. UI acting funny occasionally switching from max to low... loose driver board... and this is just opinion but it seems way less than 500 lumens. Hope I just got a fluke but we will see. Haven’t even decided on trying to return it as I see absolutely no reason the customer should ha e to pay for shipping on a defective product.
