Hey, I've found no help this far. I bought my son one of these. he is not strong enough to prime or pump anything else so far. I pulled it out and decided to try it before wrapping it for Christmas. After switching it on 3 times and empty out the darts each time, it will no longer power on. Every soldering point looks intact. Batteries were RAYOVAC brand new. In typing this I realize I could go buy better batteries. Still any feedback would be so much appreciated!!
Thank you very much
