Vitamix 7500 Blender (Open Box)

We bought this blender in September of 2016 here on Amazon. Two months later we bought the 32 ounce wet container, also from Amazon. We have been using the blender since then, at LEAST once a day but usually multiple times a day, every day. About 4 months ago we noticed some leakage around the bottom of the 32 ounce container. Since it was past the warranty, we went ahead and bought the wrench, assuming the blade assembly had just come loose after all the usage. But when we investigated further we realized the blade was actually wobbling side to side and the bottom was not loose. So the search for a new blade assembly began. You don't realize how many different types and sizes of containers Vitamix has until you need to find parts for a specific one. I couldn't find the assembly, and a new container was $150. Being in the mind set of repair rather than replace, I decided to reach out to Vitamix and see if they could tell me where to find a new blade assembly for my specific container. I just went to their website and submitted my question there. I honestly did not really expect a reply, but just a few days later I checked my email and found that they had responded that they no longer offer separate blade assemblies, but they wanted to get me blending again so they asked a few simple questions about the container and the blender base. One of the steps was to wiggle the drive socket in the center of the base and then see if it lifted out easily. It did, but not super easily, so I didn't think anything of it. I sent my answers over and fully expected a pat response that, yep, the container was broken and time to buy a new one. But to my surprise they told me the blender base needed repair and they were emailing me a UPS label to ship it, and the container, back to them. There was no mention of a repair fee, so with some hesitation that this was too good to be true, I packed up the unit and the container and sent them on their way. And boy, did we miss them when they were gone! They sent a notification when they received the unit, and the next day they sent a notification that it was on its way back to us. When it arrived, we discovered that they had replaced the drive socket and "pot switch" (not sure what that was) and given us a shiny new container! We immediately put it to use and found that the motor was much quieter and tighter, if that makes any sense. It feels like the blender is brand new, even though we didn't feel like it was in need of servicing in the first place. We were already impressed with the blender and had no problem recommending it to friends and family. But honestly the customer service blew us away, especially nowadays when it seems like the goal is built-in obsolescence so that companies can continue making more and more money by forcing consumers to replace a whole unit when just one small part of it has gone wrong. We're not sure why they went ahead and replaced the container, too, since it was past the warranty - maybe the issues with the blender base caused the blade assembly to wobble like it did? The 64 ounce container that came with the blender is still working fine, as far as we can tell, and it is only used marginally less than the smaller one. Either way, we are very grateful that they got us up and blending again!
