This is the 3rd brand of filter bag I’ve tried. My Aquabot Turbo came with 2 bags which each lasted a year. I tried to buy a replacement locally, but the pool places all gave me a price of approximately $100, so I turned to Amazon, as I always do for a price comparison. The first replacement bag I got from another Amazon seller, which was great & lasted 2 years, but immediately after ordering that one, the price went up to 4x what I paid. So again, I started a search for another affordable bag & this is the one I got. This is a great quality bag. I’ve used it twice so far. The elastic is tight and everything including tiny pieces of sand ended up in the bag. I had about 30 leaves in my pool too and it didn’t slow down the performance of the vacuum, as the bag stayed in it’s original place. I will definitely order this bag again, as long as the price doesn’t jump up so significantly, as did with the previous seller.
