Hi all. After trying to source the Samsung 3OQ batteries in the UK with no luck and with the lack of any battery offer being made available yet, I have decided to go ahead and purchase some Lg Mj1 batteries (more expensive!). I was waiting for the offer but seeing R2 just sitting there completed but not doing anything for nearly 3 weeks and also not knowing if any bits are faulty I couldn't wait any longer!
I just wanted to know if anybody has used these successfully. The specs are:-
