Got a kit from Halo. batteries worked on the first charge but never again, sent back figuring a faulty set and bought their blanks and went to e-monkey for great juices. Got the new batts and same thing! Gonna send whole mess back for refund. The N-Joys I found at local store works great but need to know where to get blank carts. Can somebody help me please? I'm back on the stinky today, yuck.
