Works good

I purchased four of these so I can work on my pick up truck and rotate tires on both my truck and my wife's SUV without having to move a floor jack all around the vehicle. These things are great and I love that they are adjustable and positively lock in for safety once raised. The large size worked well for my pick up but were too tall for the wife's SUV, a Honda CRV. They weight a fair amount but are rock solid and sturdy and more importantly are steady when raised. Removal takes reading the directions and requires a little raise and then a lift of the safety lever to lower the jack down. They work well and are well worth it if you are considering them.

The jack initially appears to be very well built. I have just purchased the unit and have not used it on a vehicle yet. Before I purchased the unijack I did a lot of checking on the lift dimensions as there seemed to be much discrepancy in the reviews. The box says that the jack is 11 inches tall at the minimum height. YES, that is the true dimension. I had replies to my question of from 11 to 12 inches. I am not sure where people were measuring. The information also states that the jack has a range of 11 to 21 inches. Again, this is true, but this wide range is only achieved by raising the jack support section. With the jack support in the lowest pin level, the jack is at 11 inches. With the jack support in the highest pin position the jack is at 15 inches. The most important piece of information that is missing anywhere is the stroke length of the bottle jack. One gentlemen was very kind to reply to my inquiry about the stoke length with the CORRECT and EXACT measurement. The STROKE LENGTH of the bottle jack is 6.5 inches. For my case, with the clearance that I have to place the jack under my 2016 Jeep Cherokee, I have to start the jack at its minimum height of 11 inches. This means that my maximum lift height is 11 inches plus 6.5 inches, for a maximum lift height of 17.5 inches. For my requirement this is sufficient with about 1 inch to spare. THIS JACK WILL NOT LIFT FROM 11 TO 21 INCHES IN ONE GO. If you start with the jack support extended to 15 inches, then the maximum lift height will be 21 and a bit inches. There are four holes in the jack support about 1 inches apart, so that is the starting point adjustment that you have. I hope that my explanation makes sense and helps some people make a more informed decision. Thank you to those who replied to my inquiry. UPDATE November 03, 2018. Well, I used this jack in anger two days ago to put my winter tyres on my 2016 Jeep Cherokee after we had out first snow in Edmonton . The jack/support worked great. Very stable, very strong. I used a modified hockey puck to sit on top of the support side. I cut two slots on one side of the puck to match the support top profile, and a small groove on the other side to accept the pinch weld. This cut is basically more of a guide to ensue the jack is centred on the pinch weld. I glued a piece of hard cardboard on the bottom side of the puck to fit between the two grooves so that the puck would not be pushed down and deformed on each lift. After jacking the puck showed not signs of deformation. Just one point. When you release the pressure off the jack and lower the vehicle, the bottle jack will NOT continue to fall down to the original starting position, unlike a floor jack. You will need to reach under the vehicle and put some force on the top of the jack to push the piston down. I only needed to move mine down a bit then could tip the jack out and push the remainder of the distance to the bottom once out from under the vehicle. Just make sure that you have the jack support stop bar lifted. I think that once the jack is used more, it might not be as stiff to push down. Still a great safe jack.
