i understand you point of view but i dont think thats the case at all, they went form v1 to v3 in 1 and a half months, so in no way are they trying to scam, what your seeing here is china not forward thinking and trying to improve what they have without making new molds, new molds can cost form 3000 to 10,000 a pop per peace that you need and the dilema is you already have 100,000 peaces of each part already.
In each one they have tried to improve, this is a fact, the bases changed form v1 to v2, they added silicone seal to botom and changed to a thicker tube in v2, now in v3 they refined all that even further and made the inside removeable, and all of this in 1 monthand a half, they didnt drag this one for 6 months raking in the cash, they saw your issues and improved on them in a timely manner.
they did this with the stardusts as well and in a timely manner, a month, not 6.
I think the ones that bought the v3 will see that everyting just fits better and works better as well. issues will always arrise but thats what we are here for.
