When unlocking the stand, if the part to be grounded is not in contact with the ground, the lock can not be disengaged and the stand can not be lifted (driven state). I feel that it is more user-friendly if I can release it with or without the grounding part.
I did not sell so much for 24 inch at the shop, even if there was even it was expensive, so I bought it. Installation was easy. The operation feeling seems to be hard. Would not it be kind as long as you describe the difference between positive and negative claws in illustration etc in the product explanation?
