Taking apart the Perses for such a small detail was daunting for me, but I am glad I did it. Not only does this product make accidental hopper ejection a thing of the past, it's smooth and elegant design fit perfectly with the blaster. It was incredibly easy to install, and Luke's tutorial was perfect for my needs. I am glad they put so much time and effort into such a small tweak, it really says a lot about them as a company
