I wanted to try another brand of lipo and they recommended me to try this one, I bought 8 lipos and only 4 have arrived. They do not respond to messages, therefore I feel cheated. I can't say more, I hope they resolve their error and complete the order, I wouldn't mind making a good assessment but today this has happened. I haven't tried them because I don't know whether to return the order or it will be even worse and I'll be left with nothing. I hope your answer. Thanks.
