Slurpies Baitfish Tubes

I picked up a couple of pkgs. of these from a local tackle shop. I go through a lot of tubes during the course of a season  and wanted to get an early start with some close out baits.  I was blown away by the detail on these tubes.  They're 4in. with three colors, plastic eyes and a scale pattern that's molded into the plastic.  They even have protuding fins along with a lateral line painted on them. 

They're distributed by Northland Fishing Tackle that also distributes Live-Forage swim baits and Impulse soft plastics.

I'm waiting to see how these baits hold up, but for the price and outright appearance. If I have to replace them a little more often, I won't be shedding any tears.

Anyone have experience with these tubes?  What's your opinion of them?
