So far just excellent.
I have made several purchases (NiMH batteries) and all of them were delivered in timely manner and excellent condition. More of that -- the newest chemistry available that is not listed in other e-shops.
For example, Fujitsu FDK HR4U 1000mAh rated and checked via OPUS BT-C100 proved to have 1074mAh capacity.
Thumbs up!
