Here's another thread discussing QuickJack pros and cons:

I have had the QuickJack 3500 ( QJ )
https://quickjack.com/car-lifts/3500slx/
It was two lift sections with a common hydraulic hose between them. I now own a Bend Pak 48" scissors lift. I left the QJs under the car when not being used, just pushed both towards the centerline of the car. I did that because it was easier than trying to find a place to store them upright.
The QJ gets the car up high enough to work underneath while on a rolling creeper. The max lift was 28"? Set up was fast - Maybe five minutes to push/pull them in place with the right rubber blocks, connect the juice lines and hit the button. I was mostly pleased with them, but wanted more height, AND the 3500 wasn't long enough to fit my son's Porsche 996 if he needed it. ☹️ I really needed the longer, 5,000lb. version. To lift, I used the front footwell outside corner locations and, at the rear, under the torsion bar end caps to lift the car. Lifting was easy and fast and the mechanical locks worked great. The red are QJ lift points. Do Not lift at the Yellow X.
So then I had a chance to buy a 48" BendPak (BP) MD6-XP 6000 lb in excellent shape and, at the same time, found someone to buy the QJ, all in one trip to pick it up. I leave the BP in place under the car with the arms swung in and mushrooms removed when not in use. Like Danny, I have placed a 2" X 12" plank on both sides to drive on for a little more clearance under the car and peace of mind when I'm pulling in or out. My ceiling is exactly 9' but I have the overhead door mechanism in the way so I cannot raise the car the full 48" because the door lift chain/center arm hits the car's roll bar, so I stop it at the third level, about 38" and that's fine - I just bought a low mechanics rolling seat at HF to zip in under the car and I just fit.
I use the normal VW lift points on the BP: Under the corner bolts at the front of the cockpit, and at the rear, under the casting that holds the torsion bar spring plate pivot point. There is enough adjustment to fit all of our cars, Acura RDX, Subaru Outback, the Speedster, my son's 996 and the neighbor's Tundra Pickup. The Japanese cars have lift points that straddle the pinch-joint welds, so I made up 4" X 4" wooden blocks with a slot cut in the top to fit over the pinch welds and used pieces of rubber workshop floor mats on top to cushion the car. Those work great.
Happy to answer specific questions, but I love my BendPak lift (just as much as Danny loves his Harbor Freight version).
