I bought this reflex hammer because I wanted one that could fit into my pocket without half of it sticking out all the time. I love the telescoping design of the hammer. The material doesn't feel cheap when extending and retracting the hammer. The reflex hammer has a good weight to it where it doesn't require a lot of force to elicit a reflex, even when the hammer isn't extended. It's more expensive than other hammers but I think the quality is worth it at this time. I was looking for this model of hammer with a pinprick rather than a sensory brush, but I do like the sensory brush inclusion. Overall, great hammer.
