BAOSHISHAN 3 Ton Double Ram Bottle Jack 6-1/2" to 16-1/2" Lifting Range Portable Hydraulic Jack with Carrying Case

Looks very well made. Strong and solid. Total height is 22.5", which is very good. The whole thing is very very big, is a monster. Very thick and very heavy. I think is designed to lift heavy equipment. I need it to lift my boat trailer that has dual axle and is about 6000 lb. But at this point i do not know if is worth keeping it. To use this only for flat tires when is need it maybe is overkill. But again i need something that can lift the trailer high enough so i can replace the flat tire, and this is the only one out there that can do the job, and have an acceptable size for storing inside the boat under a seat compartment. Again i only need this only for my trailer. I also got the electric version of a 4.5 ton, but that one is way to long to be stored under the seat. So i do not know what to do yet, but i love this thing. Is very easy to raise it and takes a little time to extend to maximum height. Again is very strong and sturdy. If you do not see another review here it means that everything is OK with it. Again looks a good product strong and heavy duty.For now 5 stars is well earned. I only had it for few days but i tried it many times. No leaks or oil spills, not stuck open, or hard to lower it down. Works good. I wish it was a little less fatter and not that heavy, but i can trade all this for the lifting height. Delivery was fast as promised. The box that arrived in was very thin and had a little damage, but the jack inside was OK. Happy camper. Thank you.

Leaky piece of junk - I was able to get exactly 1 use out of it. Oil pumped out the pump cylinder while in use. The oil release valve is stuck half open (i'm sure the O ring is jammed in there. The case came broken. Oil stripped the blue paint off that got all over my hands. I don't trust it enough to bother with any warranty.

(Update)Customer service reached out to me and sent me a new jack. I finally was able to test it out a few times and I'm very happy with it. Since I have a high clearance vehicle and I still wanted to be able to work on "normal" cars I looked far and wide for a jack like this. When my original didn't work well I couldn't find a good alternative product. I very happy with the customer service and the new jack works great. I've left my original review below, because somethings like the force needed to lift the vehicle in the second stage is still accurate.I used this pump on my 2020 Jeep Wrangler Unlimited and it worked well. The long extension helped lift the Jeep high enough to get jack stands underneath. The handle wouldn't stay in the handle holder and it got pretty hard to pump as it got higher. I remember thinking that a come-a-long bar that could fit in the handle holder would be the perfect match.Then I tried to use it again. This time on a much lighter vehicle, my girlfriend's Nissan Rogue. I was again happy that it fit under the much lower clearance vehicle, and I tightened the pressure release and started pumping. Pretty soon it got to the chassis and it would lift and lower with every compression. I tightened the pressure release as hard as I could (with my hands) and it didn't change. It looks like an internal valve has failed and its totally worthless now.The pump just sat in the case for two months. Get what you pay for I guess?

The original jack that I bought seemed to have come defective from factory. It started failing after the return period from Amazon. I contacted the manufacturer at the website noted on the jack’s label and true to their word it was replaced after a few emails with troubleshooting information. Some people may ask why I give it 5 starts if the original unit came defective (which I can understand could happen as a result of a manufacturing process), but it is because of the steps taken to correct it.

We purchased 2 of the 4 ton double ram jacks about 10 months ago. We use them on our drive on lift to be able to remove wheels from vehicles. Much easier then traditional bottle jacks that require a lot more work to get the necessary hight. One of the jacks started to leak. They sent a replacement out immediately without question. Great company that stands behind their product!

Works well as a very light duty jack. Makes it easy to maneuver.Two complaints. The top anvil is very small o.d. You cannot use a wood block; it will push right through. Be very careful even on lighter metal. For some reason the handle o.d. is an odd size and the extension will not stay attached. Really annoying.

I never had a spare tire and jack in my car and I experienced a flat tire recently and had no other option than getting my car towed which was a waste of time. I used this jack to change my flat tire. It’s very small and it can be kept in the trunk with the tire and doesn’t take much space.

Failed 1st time I used it. Kept it in my RV for emergencies. It puked oil from the seal and the slowly came down after lifting about 4". Lifting in the 2,500 to 3,000 pound range.Update. The seller responded quickly and replaced the jack. Great service. 2nd one works fine.
