I didn't realize the was a length limit to these messages. I wonder why? Anyway, I checked your link. I honestly haven't found the "real" Visions to be better than the clones. Like I said in one of my posts, the Sunrise (Stardust clone) I got from ECBlend, works the best of any of the CE4s I've tried. The bottom feels like it has a little spring in it and you push it down onto the battery. At first I was concerned that it might damage the battery connector, but it hasn't so far. The spring/give whatever seems to go away after using them for awhile.
I'm going to get one of the steel tips from Smoke Revolt and cross my fingers (I'm getting it since I'm going to try their clearos). It looks just like one I already have. I just don't want aluminum (too soft) and it looks like their aluminum ones are marked aluminum.
