I had a larger version of that given to me for pike fishing.
All I can say is that for the amount of fishing I have done with it at the location I have done it, I should have all kinds of pics of big pike. Unfortunately I do not. I wouldn't invest to much money into them, those things are garbage.
The thing is that I have caught many large fish in dirty weedy water whit this, I do have one beaten up chewed down left with a raped tail and just want to get a few more, $3-5 is not expensive, Len Thompson $5-6-7 and some lakes all you catch is weed.
Got some one getting me a few from Calgary. As for the last one I had, it's lost at the Brazeau yesterday, don't have pics cause never get in the boat but I seen the guy a few feet from the boat, it was a giant. Definitely worth the $5 without a question. If you can't catch a fish with it than you fishing at the wrong place or using the wrong technic.
