A couple of weeks ago a bop went through them,didn't get any but two flew into the bedroom window and were hurt (ok now)but finished up 7 missing.luckily I had some I was going to give away so I'm back up to 22ybs again.
A lad in our club sent his away to be repaired,the makers said it had water in it and he had to buy a new one.He asked for the old one back and said there was very little in it,would be interesting to see inside one.
