Poor service and don't care attitude from Milex

I bought my second milex nutri1200 in may 2024. One of the BIGGEST downfalls of this product is that the rubber rings inside the head with the blades does not stay in play and gets blended in with your smoothie. I tried to get replacements to fit my model in february 2025 and they sent me the wrong rubber rings. After several emails to e plain why it was wrong, they told me they were out of stock and registered my email for when it comes into stock. It's been a year now and nothing and the last incorrect ring has now been chewed up by the blade. So I'm left with a expensive paper weight or door stop. That is about as useful as this machine is. Ps the previous machine was eventually not able to turn the blades so also an expensive door stop. I guess lesson learned - don't buy milex. They not even really interested in helping me.
