I’ve never had the pleasure to use a mini-jack, but I wouldn’t mind trying out the Titan Exhaust Air Jack. The $120 bubble expands and lifts your car using the exhaust pipe attachement. The jack stays inflated for up to 45 minutes and deflates in just 5 seconds (wouldn’t want to be next to that when it goes). A simple redesign for a frustrating situation to be in. See more at Titan.
