First popper I received was defective, but was quickly replaced and works amazing. I have tried many air poppers, and this one is by far  the best and pops almost every kernel!  There is no mess to clean up with kernels going everywhere compared to traditional poppers as everything is contained in clear bowl. The negative reviews about the bowl not being secure are from people not following the instructions, the red cover at top has to be removed to allow airflow during use.
