Derminator 2 vs Dr Pen

I’m new to microneedling & now trying to decide between the derminator & dr pen. My main goal is to heal a patch of pit / acne type of marks resulting from electrolysis damage. I may move onto other areas after, but that’s my reason for buying the device so I will be going 1-1.5 mm in depth I think for my situation.

Dr Pen is obviously cheaper than the derminator especially regarding tariff tax etc, but I am seeing that the derminator is better because it doesn’t create “tears from dragging”, but what if I use the stamp method with Dr Pen? Will it be the same quality as the derminator if I use stamp method?

Also, has anyone bought their Dr Pens off shein? I’m worried they’re marked down from $109 to $50 on shein because they’re fake & not real Dr Pens.

My main focus is effectiveness & results. If derminator 2 gives better effectiveness & results, THEN I’m more tempted to pay the extra money & wait longer for it to arrive. If Dr Pen gives same results & I can reduce possibility of damage by stamp method, I don’t see the point in paying the extra money & waiting longer to receive the device.
