I purchased this jack, and the first time using it, it failed. The jack went up, but never came down. Took a video of it not collapsing when I turned the screw to relieve the pressure. Sent the video in, and they offered a $27 dollar credit and to see if I could get it fixed locally. Emailed them again and told them I needed a refund instead, and I have heard back. I get emails asking about my experience and it doesn't allow me to ask for a refund again. It's been a month, and I still have a new busted jack
