Bests & Worsts Reviews from Amazon

I've used this 5 times over 2 weeks. Followed the instructions to the letter. Didn't overfill the cup. Didn't overtighten the blade. Didn't blend for too long. Washed everything thoroughly. The fifth time I used it, I opened the blender to drink my smoothie and noticed the gasket around the edge of the blade part had come loose. No problem, I thought, I bet that happens all the time, I'll simply reseat it. But NO.....apparently that's it, the thing's done, you need to buy a whole new blade because of this 0.25c gasket coming loose with normal use. Nutribullet know what they're doing here. They sell the original unit fairly cheap, then make the big $$$'s on the replacement blades and other parts. I've heard so many other people complain about the same thing. Thought this thing was a unit of a machine at first, now it appears to be the same badly made junk everyone else is selling.
