This shot works better than most others I have used. It holds well, even on tippet as small as 7x without damaging it. The double cut feature allows for easy removal when less weight is required, and they can be used multiple times. The dispenser is also quite handy and easy to use.
This product is superior to traditional lead shot in terms of density and softness, and lacks the environmental problems of lead. In national parks and other places that bar lead weights, this product is essential, but I would recommend it on all waters for the environmentally concious angler. The one flaw of Thill Non-Toxic Shot is the price, which is somewhat high for the amount of weights received.
