Hi Natalia, Just wanted to wish you a merry christmas and give you an update on my twists. They are working great since I bought the new charger. They last me about a day until next charge so I'm happy! I recently joined a few co-ops right after the charger problem. I-m getting a new z-max in one of the co-ops and some
rba's in the other two. They will be here this week! I'm really excited. I will use my twist on the road and as back-ups(still love them). So just wanted to give you an updated, take care.
