I’ve had one for years, they work very well just take your time setting them up to make sure that they are even and square to the car. The centre of gravity is about 2/3 back on the doors so make sure you have the Jack’s back towards the rear wheels .
If anyone is interested I have a Quickjack Hydraulic unit (DOES NOT INCLUDE LIFT FRAMES) still in original box-includes everything except the frames-hoses blocks etc etc-brand new- never even taken out of box-my quickjack arrived with damaged hydraulic unit so they said they would send me replacement-after 8 months I gave up hope and had my damaged unit repaired and tested and then low and behold the replacement unit showed up on my doorstep-I see one can buy lift frames for $900+CDN from quickjack Canada depending on which model you need. THe hydraulic motor is listed at $569 plus taxes and shipping plus I have hoses quick connects, blocks etc so ball park $1000+ - more than happy to entertain offers way less but reasonable-In Horseshoe Valley but could ship as it is still in box at buyers choice and cost.

I have the new 7000 from Costco. I ordered the extensions direct from QJ. I will set up a homemade ramp(3”) so I don't have to jack the car up. The extension kit adds 2” to the basic height.
