Product review (5 stars): Fits VitaMix 5200
Total time spent including bringing tools into the kitchen, disassembly, reassembly, and test run was 30 minutes max. The toughest part was getting the 2 case halves separated due to the rubber pieces around the edges between the upper and lower. The old switch was faulty to the point that my blender had fallen out of use. Now it works perfectly, and is used several times a week once again! Very satisfied with its performance so far. It's only been a few weeks since I put it in. I'm considering buying another to keep on hand if or when this one fails (assuming I could remember where I store it!)
