Review on ARANA 10-inch 45N/10LB Gas Struts Cabinet Toy Tool Box Lid Cover Lift Support (9.69" Extended, Suitable for 8-11 LBS Weight) by Chris Jens

Good posts, good price, BUT: There are two different brackets for each post, one round and one rectangular. Which is above, which is below? I've tried both ways. They are not interchangeable. By the way, the rectangle comes up. WHY isn't that in the instructions? They say "allow an angle between 90 and 120 degrees". From where to where? You only have to guess. I spent an hour installing two spacers, which should have only taken ten minutes with the right instructions.
