I've had the new Sigelei 24 hours now. I have dressed the threads with Noalox. I took some time to clean threads on my older unit, too. Noalox will start to harden up after a few months so it's a good idea to clean and reapply once in a while.
Just to recap, I now have two Sigelei Zmax V3 Telescopic flat tops. The first was purchased in mid-April and still works great. The second arrived yesterday. I wanted a back-up unit.
Sigelei has upped the game with small changes to this model. They have not changed the version number. It's still V3.
1. The tube threads were perfectly clean and smoother with the new Sigelei. The older one squeaked like a rusty door until I cleaned out the threads.
2. The new production units have a removable top cap for easy cleaning of the 510 and eGo threading. The eGo threading on my older unit is brass. The new eGo threading is stainless steel.
3. Not much of an improvement, but in Menu Item #4 the wording is Batte Voltage on the older unit. On the new model the wording is Batter Voltage.
4. On the new production model the color underneath the plastic button is black instead of grey.
5. On the new production model the OLED is set deeper into the tube. The newer OLED display is brighter and tinted closer to blue in color.
6. In Menu Item #5 the words "Resistance" no longer scroll along for long time when selected. With the new model it doesn't scroll at all. It says "Resistan" and stays lit as long as other menu selections.
The new unit is on top. Both have 18500 inside with the 15mm battery cap installed.
It's easy to tell which units have the new removable top cap. Look to the left of the display screen. A flange from the new 510/eGo connector assembly shows up between the top cap and the main body. The blue tint and deeper position of the OLED screen is not that noticeable in this photo. The OLED was slightly crooked on my old unit from day one. I decided not to sweat that. The new unit is on top.
