Query: Don't waste your time and money on this

The first time I used this product, it worked great! This is the only reason I am not giving it a 1 star review. The second time I tried to use it, I popped in the microwave for 2 minutes. I thought this was not too long, according to the package directions. When I went to pull it out, thousands of little beads came pouring out of a hole in the corner. What a mess! This product is hardly well made if it cannot withstand a single use. Don't waste your time and money on this product. It is not well made at all.
