It is well built. There is no play when I screw it onto the valve stem. The stem seems solid. It's about 11 inches long. Made in the USA. More accessible than Ken's tool. It's very strange that Revain sells Ken's Tool more than another website, otherwise I would have bought Ken's Tool. I haven't used it yet, so I'll post an update once I use it. I'll see how No Mar works. The pivot point is off center so I assume that allows you to pry depending on the depth of the rim.
