Let me start by saying these Mimilure PVA bags are a solid choice for any angler targeting carp or catfish. The medium size (8cmx16cm) is perfect for holding a good amount of bait while still being manageable to cast.
The dissolution time is impressive - they break down in about 90 seconds as advertised, creating an effective bait cloud that really attracts fish. I've used them in various water conditions, and they perform consistently well.
What I love most is the convenience. Just fill with your favorite bait (I've had great success with chicken liver), twist the top, and cast. The welded seams hold up during casting but dissolve quickly in water.
One pro tip: If you're having issues with floating (like one reviewer mentioned), simply add a small stone or sinker inside the bag before casting. This solves the problem completely.
The only minor drawback is that sometimes a small amount of residue remains at the twist point after dissolution, but this hasn't affected my fishing success at all.
For the price and quantity (100 bags per pack), these offer excellent value. They've become a staple in my tackle box for both carp and catfish outings.
