connexion x2

Hello to all! I have read and learned a lot from this form already but this is my first post. I got a connexion x2 about 2 1/2 months ago. I carry it everyday and when it works I love it. However, it has acted up several times and I really don't trust it. A handful of times it has just shut off. The first couple of times this happened I just wouldn't use it for a while and the next time it would be OK. More recently I have learned that if I loosen the head it will turn back on. Also sometimes it will flicker while it is on. I am using E2 batteries, and switching them doesn't seem to help. I also use it with the TurboForce head and primarily run it on high. Is there something I can do to fix it or should I call Battery Junction and see what they can do? Thanks in advance.

You might try Deoxit on the contacts to see if that helps........
