The previous post have all my questions and conclusions. The post you quoted was an answer to the question of upper heater height.
Here is the post that needs addressing:
I find the direction and lack of details about the Jovy 7500 disturbing. It is as if the members promoting this machine are using a magical method that can only be taught by trial and error... the trail and error of each individual that has already purchased an Jovy.
This makes no sense. If there are members here that own a Jovy and have used it to reflow (NOT A REBALL) an Xbox 360 or a PS3... then let them come forward with profiles and detailed tips. It is not that difficult to pass on. The Jovy only has 3 sections for profiles... Preheat - Reflow - Fast Reflow, and the temps at which to end each stage. The height adjustment is measured with markings like a ruler... So there is NO ROOM FOR ERROR!
The most of the videos presented here are commercials from Jovy, and most misleading, as the only time the machine is on is the reflow of the reballed GPU. Or... the temps are too low to reflow!
This video is an "ad" not a proof of process.

Now, I have a Jovy. had it for 2 weeks, had nothing but trouble from it. The profiles provided for PS3 and Xbox 360 are from other owners and not Jovy! How can a company state that their machine does something that they themselves have not done with it?
So, if this jovy 7500 works then back up the hype with facts and details.
