Ha, yes. It had been a long time since using a jack and had only used the one included in the trunk. All good, literally filmed on the first use of the jack (and the stands; primary purpose of the vid).
They look AWESOME... the only issue i see is all the weight are on those pins .... Not sure how strong those pins are SUPPOSED to be.. Maybe find a place that can pressure test those pins or put that jack stand on a vice and crunch it down to see what point those pins fail ...
Those type of pins have been being used for 50+ years Check out this review My problem with the jack stand is shipping cost Anyhow, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eE6HzErxMxY.html
