Thanks for the extensive review Adam!
On the methodology can you confirm how you’ve done the extensive battery test in water bucket? Shooting lots of continuous full power flashes wouldn’t have been possible (well, depending on the frequency) on the Z240 due to heating, so it looks like Inon did address well the heating issue on Z330?

The EV stops are in brackets as is the STTL mode indicating that these two are linked. EV stops are +/- 2 stops and correspond to compensation in STTL mode. 
Power from 1-100 is in percentage and is used for manual modes (ON and SL). Big dots indicate a 1 F-stop increment whilst small dots indicate a 0.5 F-stop increment. Only between 25-100% do we have half stop increments. 
Did you get the practical instructions sheet with the borrowed strobes? It's one A5 piece of waterproof paper which you can take in your dive box and explains these basic features as well as different modes and maintenance.

Thanks for these explanations Oskar, i didn’t get the instructions but it’s all clear now.

On my current Inon z240 i have always 0.5 stops increments, so i know by how much i’ll add/decrease the strobe output when manipulating the knob, even without looking.

Out of curiosity, what’s the reason for not offering 0.5 stops increments below 25%?
Is it because you’re assuming most people would use these low powers only when getting very close to subject, and at these distances strobe power needs to be decreased quicker?

One more question to you Oskar if i may, but i guess i won't be the only one wondering: on the Retra flashes i've borrowed i see the following power levels: 100, 50, 25, 6, 1, and corresponding: +2, +1, 0, -1, -2, which i guess are in EV.

For the 1st scale i am confused: from 100 to 50 and 50 to 25 that's -1 EV (division by 2 if i am not wrong), but i don't understand the jump from 25 to 6 and then 6 to 1, which are also spaced by 1 EV if i am reading well.

Hi Nicolas
We suggest lubricating every 10 times the battery compartment is opened/closed. The o-rings don't need to be taken out if they are clean and without dirt or debris. We supply a silicone grease with the Retra Flash although any silicone grease is useful for lubrication. 

Thanks for this Oskar!

Hi guys, what sort of routine do you apply for the retra o-rings:
-Lubricating each time you open battery compartment?
-taking out the orings to do so?
-with which lube? I have hips of inon grease...
