So, of the issues I have read about the unit so far, there is the QC on the tips--something that they will probably "iron" out in the manufacturing process.
Secondly, the rubber O-ring/gasket that is friction fit inside the handpiece not staying in position, moving around, etc (first mentioned in post# 266 by Dolivas) -- are thing going to re-design this?
Finally, we have the firmware upgrade to lower the minimum temperatur as well as being able to buy the unit with the instant setback stand--that should just be a matter of time. Is that about everything?
