Nice info link there about the universal adapter for UK. In our place we also have that but ours is the universal (female) to US-type. Thanks
Hi everyone………
we arrived at fifty.
we can proceed to payment……yes…no…
Dora, my contact person in this gb, was on sick leave since Friday. Before going on sick leave Friday, she Skyped me that she will be reporting for work Monday, April 28th, HK-time. I will ask her on that date the coupon code to be used, and will be posted in this thread.
Funniest thing I read all day.
In for 2 pending HKJ review.
I would buy it if someone could confirm that there really is working internal switch to charge up to 4.35v. 
I found this pic! . It’s shame that this switch is really hard accessible.
I’m in for 1x, USA Plug. Hopefully HKJ’s testing shows a measurable improvement on some of his concerns.
I’m in for 2 units
No problem. With the firmware upgrade to V2.0, a complete set was instead sent.
Perhaps this link can answer your question: (excerpts below about the 4.35V)
http://www.mountainprophet.de/2014/03/15/preview-akkulader-opus-bt-c3100/
Since I always have some battery tests are missing for dampfakkus.de with 4.35V, I have tested quite extensively also to 4.35V mode of Opus. The batteries were reliably and accurately charged to the specified voltage 4.35V without any further problems, no matter in which slot and also at 4 * 1A full occupancy. As expected then showed the battery (of course only those that have been certified to this high charge voltage!) In the discharge curves corresponding results. The 4.35V mode is therefore not a marketing gimmick, but brings with suitable batteries a real added value in the form of better voltage curve and increased capacity over the entire duration of the discharge. In the handling of the Opus is anyway to worlds more comfortable than the Cotton Picker loader previously used by me.
LiFePo I have not tested because I do not have LiFePo batteries.
Already hit 50…how to proceed from here?
Please read post # 109.
Thanks

Has HKJ reviewed Firmware 2.0 yet and confirmed all the initial problems have been fixed?
lionheart_2281, as far as I know, they shipped a 2.0 version to him 3 days ago. So he still don’t receive it, then no Firmware 2.0 version review from HKJ yet.
tatasal, do you know if this coupon code has expiration date?
Ordered. After you go through the Paypal screen and go back into the Gearbest site to finalize your order, make sure you click the checkbox for free tracking.
