“I bought the Blu Pro vape pen to replace an old one which eventually started to hold the charge less and needed recharging too often. This isn't a criticism because the old pen lasted a very long time which is why I bought the same model again. The reason it loses one star is because the replacement mouth pieces sometimes develop a leak. If they could fix this they would get 5 stars. Overall the pens are good value for the money and are a nice size to pop in my bag when I go out.”
