Just got my drip tips from Cloud9vaping today and just have to say I am very impressed with the quality of these things. I got one of each type and the cone shaped one fits the eGo very well and looks like it was made for it. The straight one looks quite nice on a regular 901 or 510 atty. They both have a funnel shape to the inside to direct the juice to the center of the atty. I will be using them quite a lot!
