Has anyone used these? I am not looking for a long lasting solution or high production molds just something that is cheap and produces a good bait. 

Thanks

Ben,

I have them.  I have a lot of trouble with air bubbles.  Haven't quite worked out how to avoid them. And the plastic is hot when you're trying to work with them so that makes it difficult.  I've injected plastic until the mold is overflowing, but when it cools an air bubble forms.  If anyone has worked this out, I'd love to hear how to avoid/fix it.

My opinion, and I did the same thing you did! I had 5 of the molds your talking about, and my suggestion is to buy a used injector from somebody, and get one of the $30 essentials series from do it baits if you want to go the cheap route. I tried the molds your talking about...and I don't think I ever made a good bait with them. It is so much easier when we spend the $75 or so to get an injector and mold...now we have about 12 molds and multiple injectors...good group of guys on here too...lot of expertise that helped me get started 

I got 2 Do-it OP molds and love them. The aluminum ones will last forever also
