I have ordered 4 packs from them and have had no problems at all.. About 2 years ago I ordered one 8 cell Tx pack, and three 4 cell Rx packs. all came to me in great condition, and all are still in use today! all still over 85% rated capacity!
Personally, I would order from them again!
P.S. I have also ordered 5 cell Rx packs from Onlybatterypacks.com and they gave me great service too! I wouldn't hesitate to order from either of these companies again!
