I have had my 372 " p3000 version 2" for about a week or so. It does seem to gain then lose but it seems to equal out at the end of a wind +/- 2-3 minutes. I lay it on it's caseback when not in use, I have not tried it laid on it's side, that might be better. I have had no issues and am impressed with the P/R, I hope I didn't just jinx myself..:0)
