We had the same size Chuckit! launcher, but our puppy got a hold of it so we had to get a new one.  This one looks the same, but it doesn't quite throw the same.  Not sure if this is an older version, but there's something different about it that makes it different to throw and we don't really like it.  We may try to buy another one from the local pet store to see if that's like the one we had before.
