The release valve is integrated into the handle, which you twist when it’s time to lower the pump’s hydraulics. The handle has a comfortable grip, and the low-profile jack easily slid under our test vehicle. While the instructions included with the Blackjack are practically useless, it isn’t too difficult to figure out how to assemble and operate this floor jack. There are also reports that customer service is slow and difficult to contact. While this isn’t common, there are multiple complaints on Amazon about this specific issue.
Some people received the Blackjack with parts missing or with broken swivel casters. It is easy to maneuver with a long handle. Many are impressed with the value given the relatively low cost of this car jack. Those who like the Blackjack appreciate its heavy-duty construction and low-profile design.
