These lucky ducks are bulletproof... One of the better spinners on the market IMO. Just a great price too. Use promo code 4GIFTS and get free shipping!
There are definitely more birds nowadays that shy from the spinners than ever before. They have their time and place. I find that they work best on bright sunny days. More and more I find myself using a jerk rig instead of just a spinner... but the spinners are a great tool on certain days.
