Ummm. I Just buy Senkos and Roboworms, and no problems. I have had some others melt. Zoom worms, elaztech Strike King worms. Don't mess with them too much anymore. Not for the melting. Stopped using them because they simply suck as a bait. Haha. Strike King is for rage tails and rodents. Zoom for flukes. Worms? Senko and Robo. No sense in trying something else when these ALWAYS work as advertised.

Also, I shouldn't have to read the instructions for a bait. It is kinda obvious. Lol.

I had some small swimbaits of there's melt as well.

I bought some Z Man trailers from BPS. Didn't check them in the store. I'd never opened a brand new bag of deformed soft plastics before so didn't think to. Took them home and either threw them in my boat or hung them on some peg board, can't remember but I do know I never opened them. First time on the water I opened the bag and they were all deformed. Not to the point of unusable but they were flattened.

Maybe the boogieman put a zoom worm in there when no one was looking.
