Very popular product with good results.
Saggy Bags are worth the money. You may have to trim the side inserts to fit them under the seams. Fit them as tight as you can, I had to start the inserts at the base of the bag and using a block of wood and hammer the insert tward the top. I used lots of clamps on the lid inserts to remove any bumps, just sitting heavy objects on them as recomended does not cut it.
