Yes it has lots of pressing power, but the ram moves quite slow by either air or hand - the extreme amount of pressing power is a good trade off though.
A great thing was once we opened the decently built crate the press was nearly assembled complete, only had to bolt on winch, pump, and feet.
Yes it is built very heavy to use 50 tons of pressure, but it's a cheap type of design such as the feet are way to light duty, the cable winch works but needs a stand off so it doesn't rub hard on the clamped end of cable, the cables are too far in taking up a couple inches of open pressing room - a simple tab or angle iron relocates the cables out of way much better. Definitely built in Cheap China.
Overall it's a great value but remember you're getting what you pay for. It's built very heavy and weighs over 500 pounds, easily presses over 30 tons almost effortless and definitely uses the 50 ton ability when pushed.
I'm happy with my purchase and I do recommend it, but I'll be making slight modifications to mine.
*slight side note*
My press was shipped without any nuts to the hardware, supposedly they're shipping the metric nuts to me over a week after delivery. Obviously I just used standard hardware that was available to finish the minimum assembly.
