I have read a review on the merlin RTA and all seems positive however I have come across one or 2 videos on YouTube where they say it has a slight whistling sound when vaping and they find that annoying - has anyone found this as i keen to purchase one

I guess the big factor is probably the 2ml of juice it holds - might be good for at home but not good for on the go and need to constant refill as i do vape a lot
