Query: great!

These little life savers are awesome. We bought these after my father rolled his stock truck and was upside down stuck in the seat belt. incredibly the windows did not break out during the wreck. So he found himself stuck, upside down, with gas and antifreeze leaking everywhere and unable to get out of the truck. Thankfully one of the windows rolled down, and he was able to escape unharmed. So we have now equipped everyone that we love with these life saving devices. My father has equipped the entire EMT/First-responder groups in his rural area with them. Thank you for a great product.
