Query: Exploding pods!!

I have had at LEAST 10 pods explode while brewing. Coffee grounds get everywhere in the Keurig making it necessary to take it apart and clean out the wet grounds. There are also a lot of grounds left in the bottom of the cup. I'm on my second exploding pod today. The taste of the coffee is great but the mess is awful. I will NOT buy again.
