Query: Extremely Disappointed!

I have been looking for a good popcorn maker for some time, and when I saw this one, my eyes widened. It looked nice and it was only $30 so I did not think twice about getting it. However, after using it according to the instructions, I was disappointed for several reasons.When popping, the kernels flew everywhere, despite using a large bowl. Even though I measured 100 grams of popcorn kernels, as recommended in the manual, more than 50% of the kernels remained unpopped and wasted when the batch was made.The machine looks nice, but it is an absolute piece of junk.
