I have 2 things to say: First, I could not be any more pleased with the $40 jack I got from Harbor freight that has given me NO problems. It's a 2.5 tonner and it's either Central Hydraulics or Chicago whatever brand.
Second, Torin Big Red jacks are horrible, I purchased the BEST jack that pep boys sells for around $100 (3.5T Torin "big red). Except the grease fitting wasn't threaded. Returned it and got another, this one didn't lift, but at least the grease fitting was threaded. Had air in it, added fluid and bled, got it to work ONCE before spewing hydraulic fluid all over my workspace. Called up Torin's warranty line, they told me since I'd had it under 30 days to take it back for a replacement. Got another one from pep boys, opened it at the counter, the greasse fitting was not threaded (I thought it was the first one I got except the box was sealed and I had cut my box), so I left that one there, went to the shelf and got another one, came back, opened it and made sure there was no air, then convinced the manager to let me try to lift his Explorer with the 'working' 3.5T jack. Got it up about 4-6" and the lifting slowed, then stopped, then it dropped the car. They refused to refund my money, I told the manager he had to give me cash or store credit, so I got a nice ****** air compressor. Now that pep boys only sells the light duty aluminum jacks.
