Was great at first. I mainly use the Rocket Blender to make smoothies in the morning and I use the large cup.I made my niece a smoothie one morning using the smaller cups and none of the plastic rings would fit on ANY of the smaller cups. They were all too big. Until that point I had only used one of the large plastic cups and one plastic ring.Today I made another smoothie in the same cup I always use, and the ring kept popping off when I went to drink it. I've only had this for 2 wks and don't even use it daily.It's going to be exchanged for the Magic Bullet.
