Ovo ja zvanicno obavestenje od Umi:
navodno im je dobavljac uvalio slabije baterije.
First of all, we thank you very much to all our fans who have informed us with the issue on some of our UMi Hammer batteries. We appreciate it very much.
After investigating the issue we have found that our battery supplier has been negligent with the first batch of UMi Hammer and supplied the incorrect battery size. Those of you who have been affected are asked to contact the store you bought your UMi Hammer from and request a free replacement battery.
We apologise for the inconvenience and assure you that the will not happen with future UMi Hammer models.
Nažalost i kazna izgrađuje stav!
