The S5 Max Main Brush is an OEM but it was not mentioned anywhere in the description. The brush is not as soft and neat as the original and spread out unevenly. Hopefully it does not scratch the wooden flooring. However this is still the only part I can find that fulfilled the requirement of S5 Max. Can't find original parts anywhere (even the Shopee Official dealer), so this is still the best deal I can find for now but OhMyMi should update its description to mention that this is an OEM part, not original part. At least we pay for what we thought we have purchased (I would still purchase it as I need that part that I can't find anywhere else).
