I was impressed by the kindness of you and Yihi Electronic co and, I will remember without forgetting. If I upgrade my product in the future, I will surely buy your product. I will share the e-cigarette members of Korea with excellent service of Yihi Electronic co.

Very impressed with your build quality- my sx mini ML class survived flying 15-20 metres at over 30mph when I was knocked off my motorcycle in April. It was in my top pocket! I broke my foot,bike badly damaged & the car that hit me was written off,but my beloved ML still functions perfectly, albeit with a few cosmetic battle scars! My iPhone,which was in a tuffbox protective case,didn't fly as far but was wrecked- very impressive Yihi ??   Keep up the superb work, best mods & board on the planet! Thankyou, Respectfully Steve Fox
