Query: Coupler broke in less than 5 days

This blender looks beautiful, love the copper look.It really fit well, with the things in my kitchen, and looked great.In less than 5 days, the coupler that connected to the blade, sheared off.It seems that it is held together by glue. My old Commercial blender has been in operation, for 10 years now, and still works - just a bit tired.We ordered the Cuisinart Stainless 600 Watt blender, hope it works better, and lasts longer than this.If you are interested in the copper model, look for the comments, under the chrome version. I missed the negative comments there, until I had the failure.
