POOR QUALITY OF KITCHEN MIXER

I have always purchased Cobra taps. Last year I purchased a Cobra Mixing tap for my kitchen sink as we changed the washers too many times and found that we needed another tap. However, it’s not even a year, I had to purchase another unit, because after changing the washers 3 times, we found that the water was dripping too fast. This is getting ridiculous to say the least. I am 66 yrs old. I have never experienced this problem of replacing mixers as I am doing in the past 2 years. This has to be poor quality of the mixer, and nothing else. We are seniors trying to make ends meet. This morning it cost me R800 for another mixer. I am very disappointed and upset.
