My opinion is that the CE4+/stardusts have a few more rounds of evolution to go through before they are truly ready to replace my CE2s. The CE2s went through the same type of deal and I expect the CE4+s to travel the exact same path. I only ordered two of the latest batch, I was initially impressed, but some of the issues started to come through. A) They cost about $7ish a piece B) Have tendency to develop cracks C) Do not come apart as easy as others D) Can exhibit burnt taste. A good bit of these symptoms only happen on some units, but at $7ish a piece thats a gamble I am not willing to take considering I can get a pack of 5 CE2s for $9 bucks, and if one is faulty, who cares, toss it. The CE4+s do a lot of things right, they are just too much of a mixed bag now. When they perfect the manufacturing I can see myself moving to those full time. Until them, its just me and my CE2s.
