The jack arrived a head of the predicted delivery date. I was pleased about that. I have 2 compressors one a small portable one with a small tank and max 100psi, this lifted the back of my pickup with ease. I was so impressed I ordered the 5 ton version which arrived within 4 days. A great service. My drive is gravel and trying to use a conventional trolly jack is almost impossible. These jacks slide under the truck with ease. Great product great service well done.
