Query: Not to sturdy

I can't deny it really does make a great cup of coffee when it works, the best.But every single one I've bought (3 in 5 years) I've had to get replaced, Keurig has been very good about replacing them, but come on, every single one.The replacements work about the same so when you start doing the math, don't wince.I'm looking for a replacement brand and would love to hear a recommendation, I still plan to drink k-cups.
