Aerial Ballast bags any good?

Just curious if anyone has used these before? Im still new to boarding but found these and may keep them in mind for the future. Just wondering if anyone has used them before? Too cheap?

Thanks!!

They look like the old style Launch Pad bags with waterbed fittings.

The bags do use the water bed style fitting, there are definatly better fittings on the market. I have the 550lb version of these. The constuction is good. I have a hard time getting the bag 100% full, typically I get 70%. If you looking for cheap, they are hard to beat.

I have two of the 350lb ones. They can be a pain with the water bed fittings, but aren't bad for the price. Construction is decent. They have an inner bladder and outer cover. The bladder likes to move around and can be an issue. Otherwise you can remove the bladder and use it without the outer cover.

I also have two of the 350 lb sacs. I bought them back when I wanted cheap ballast for my I/O. Now I have built in ballast in my current boat so I just keep one of them under my bow cushion filled at all times and the other one is a spare I'll use for surfing. Like LightningRon said, the inner bladder can move around inside the cover so the valve doesn't align with the hole in the cover at times. Also when the bag is full and you're taking the cap off to hook up the pump to empty, water shoots out until you can get the pump hooked up. These things aren't a huge deal, especially for me now since I keep it filled and never deal with filling and emptying them anymore.

They do what they're made to do, hold water without leaking. I would recommend not getting that package deal. Buy the ballast bags and pick up the Tsunami 1200 gph pump instead of that 800. Trust me, the faster pump is worth it. Just make sure you get one of those blue waterbed fittings with it.
