OVERALL OPINION

My opinion will be very fast! and very clear! It's m *** e.
I bought two for overheads.
I've used one once and then put in a box for the hardware.
Then I opened the box the round plastic main (center) broke down, the thread also smashed.
I make no clamping force, I have prepared well in the box.
Lightweight plastic ... short go your way I can tell you, you will lose your money.
