I purchased 2 of them and used them last week up in canada. They work great with a lure that has its own action. Less drag when pulling them in. Now the down fall was stacking my downriggers with 2 poles on each side using the fish flash on the top two poles. If you get the two lines together the fish flash will make the biggest twisted up mess you ever saw. Line cutting start over tangled up mess. I wouldnt hesitate to use them again but with only a single pole on each downrigger. I finally switched back over to using four flashers for the rest of the trip they can get tangled but never as bad as when that fish flash was involved. We also used a bait buster for the first time and I am impressed by the end of the trip the velcro wouldnt even hold together from all the fish it pulled in. I bet it had over 60 fish to the boat in 6 days and countless more lost after the strike. It works great with the fish flash.
