This ball is very good for its intended purpose, which is dry lanes.
I have had this ball for only a couple months, and I have been easy on it. It is not my only ball. I generally carry 3 to 5. And I rarely use the same ball for 2 games in a row, so it has been used lightly. I work at night, and have been bowling in a morning league where they do not oil. Wood lanes, well kept and clean, but dry as a desert. I bought it for this league, where everything else was over-reacting.
The Razyr is about the best of the dry lane balls I own, and worked very well on this surface, getting down the lane and giving a smooth and consistent reaction when nothing else would stay right of the headpin. A previous poster wrote about this being a very condition specific piece, and I agree. It likes dry, and works better the drier the lanes are.
My only knock on the ball - aside from the girly colors, which I can get over - is that it seems to be a bit less than durable. I have only owned the ball a short time and have played the ball fewer than 20 games total, at a house that is well maintained and is not exactly known for beating up equipment. My Razyr has taken a ridiculous beating, and has numerous scars, scrapes, and damage - some pretty deep. A ball with this few games on it just should not be this beat up, in my opinion. And it seems to take more and more damage every time I play it.
Overall, this is one great ball for dry lanes. It gets down the lane easily, even when that is a problem for other balls, and it does not over-react. But if you really like it, better buy several, because it seems to be too soft or too fragile for everyday use, and it apparently takes damage way too easily. If this were my only ball, I don't think it would survive half a season before having to be replaced.
