Product review (4 stars): Saved me a LOT of money!
Perfect for broken Magic Bullet! They came quickly and were reasonably priced. We had to watch a video to see how to put it on and it took two of us to do it -- but, we got it on and it works great. Here's the video we watched, there are several of them. https://www.youtube.com/watch?v=SBrNyGVnkqY
