Query: chunky smoothies, blade assembly seizes

Somehow stuff gets missed by the blades. You get big chunks of banana in your smoothies, and big rocks of ice in your margaritas. Unless you blend it for a way long time (like two minutes).The first blade unit seized in about 4 months. 15.00 plus shipping to replace. The second seized in about a year and a half. I may give up before I buy the second blade unit. I have had other blenders that were way more effective. The overall idea is great, a dual purpose unit with a wide glass jar, and an easy to clean control panel. If they would redesign the blade unit, it could be a great blender.
