Hi Nemrod
I’ve been using Retra since 2020. Yes, pricey but I’ve never regretted the purchase for a second. I’ve gone through various iterations and now have the ProMax with the Booster. They are a very neat package and not much larger than the venerable Inon Z220/240. The Booster is especially ergonomically neat and a much better battery change arrangement than the SuperCharger.
On use, I find using an LSD snoot - which I do almost constantly for macro - the Boosters are essential. I often have the power cranked up. I reckon on getting 3 dives - say 400 images - during the day with some power left over with that setup.
I find the Boosters useful if I'm shooting into the sun a lot with wide-angle and using HSS. In those circumstances I often have the power setting pretty high.
However, on bog-standard wide-angle shots, although I have the Booster in situ (why wouldn’t you?), battery life is significantly longer.
No, with APS-C the Retras are not overkill. I’m shooting a Nikon D500.
I’ll happily admit to being a Retra fanboy. An excellent product that delivers power and quality in a manageable package with excellent accessories and terrific customer support.

When I made my first batch - which led to the original article - I used scissors. The cables worked perfectly in Manual with my Retra strobes. But not in TTL (which I rarely use). It was a conversation with Oskar at Retra that highlighted that scissor cuts were the issue. I recut using a box cutter (aka Stanley knife) and the TTL issue was solved.

Problem with Retra Pro X
in Lights, Strobes, and Lighting Technique
I think that's the over-heating warning
I pulled this off ChatGPT:
This happens when:
shooting long rapid bursts,
using high power repeatedly,
using strong modeling/pilot light,
or in warm water/air conditions.
The strobe will automatically:
reduce flash power,
limit the pilot light,
or temporarily stop normal operation
to protect internal components.
What to do:
stop firing for a minute or two,
turn down pilot light brightness,
reduce burst shooting,
let the strobe cool in the water.
Once temperature drops, the blinking should stop automatically.
Retra specifically recommends shooting in intervals with 30–60 second pauses if you’re pushing the strobe hard.
Oskar might well chip-in.......
