Although I can't rant too much about a blocker, these are great. Out of any parts of my 1X set, I have 0 complaints of the blocker. It does it's job, and it does it well. My palm is still great, a year in and standing tall, compared to the other 1X pieces. Definitely worth a try.
Super light, keeps its form, and easy to direct shots to where you want them to go.
