Review on Vented Microwave Silicone Hardened Tempered by Heather Armstrong

I've been using it for about a year and up until this morning it's been great and dishwasher safe. when it exploded! I ran the dishwasher inside last night (just like before) and unloaded it this morning when out of nowhere this lid popped and glass fell EVERYWHERE. I was locked in my kitchen with shrapnel covering every inch. The photo I've attached is after cleaning the floor and some shards in the dishwasher. I was in total shock, I don't even know how this could have happened, thank goodness it didn't get in my eye etc. I nearly cut myself cleaning up the pieces with gloves on - I couldn't finish cleaning there I had to go to work and didn't have time. It's insanely dangerous and I'm still in shock that it happened. I would be very happy about a return.
