I have one (orange) 20 years old. Modified . Have a hand crank to raise and lower the table. Too hard for one old man to do. Have an air powered jack. Too much time for one old man. Have only so much time left on earth. And, I have used the s... out of it. Bent the dowel pins that support the table but, oh well. I can straighten them(and did). Would I buy another?? Absolutely. It does not have a pressure gauge to tell you how much pressure you are exerting. If you can't tell by resistance to the handle, don't do it.
