The only positive is that the aluminum is rigid and the price was right I ordered the 6-9. As usual with amazon prime returning them was easy. FOR MANY YEARS NOW I HAVE BOUGHT A NEW PAIR OR TWO EACH YEAR (. This charger is exactly what I like. I purchased this spice rack as a gift and when it arrived, the metal was bent so one of jars would not fit into the hole. I really wanted to like these, but the extremely limiting tilt adjustments meant that I simply couldnt comfortably enjoy these, and I had to sell them. Easy to setup and take down. Id give that puppy 5 stars. Mounts easy and precise.
