It aligns and seats well. It is better than the old one I can't find without the pin. It's been effective on expensive and very, very cheap cassettes. It's machined well, but won't blow you away. For that I'm still not going call it a an awesome value.
Can't perform the procedure without this tool, which pays for itself with the very first use. Seems durable enough for years of use in the future, even if used at a pro shop.
