Say I bought a smoothie blender from catch. After the first use I noticed the jar has a crack. When I contacted the manufacturer via catch messaging for a replacement, I was told I will have to ship back the jar for an assessment as the manufacturer cannot certainly say if its a manufacturing/material defect or users negligence ("May be you dropped it - may be you tried to blend rocks").
While the manufacturer does have a valid concern, I am trying to understand how does a consumer really prove that they have used a product as per recommendations?
The actual product in question is a wet grinder - since its a slightly regional item I have substituted the grinder with a blender in the question above. The grinder is used to grind soaked rice/pulses/etc. The base of the drum (from the inside) has developed a crack after literally the first use and it weighs a good ~5 kilos. The manufacturer wants me to ship the drum back as they want to assess if its manufacturing fault (no idea how they'd do that). Looking at the tone of the messages so far, the manufacturer is bent on proving that I have somehow damaged the base, where as I have used it very carefully - its a ~$300 purchase - and its cracked while in use. It's what $20 to ship - and I think I will take that route eventually - but very curious to know how does a user prove they aren't at fault?
Last time I blended gravel and rocks it didn't crack the jar.
