Main issue is the safety lock pin loose fall off during work out, then I just realize the lock pin so loose, Maybe this item I received just a defect one.
But I wont put my life at risk over budget equipment.
I just notice the lock pin only able to plug into 4 weigh plat from top. Ant lower too tight seem the size of the weight plat slightly larger than the rod whole so they not align. I just realize these plate are not metal so they are not precisely like the metal cnc clock.
It difficult to plug the log pin from front as the string and join pulley block is right in front of the lock whole, they need to redesign the string and join pulley positions away from center of the weight block.
The small footprint is nice for compact space. With the value for the money, might be work for any one who look for budget friendly, and big IF, IF you get the item that lock pin is not loose and you are handy who doesn't mind load weight by plug pin block from back of the weight block.
