Great product, but it's caught everything but my mantis shrimp
It's a great product. It should come with instructions (not sure why they aren't in the box) or at least the vendor should create a YouTube video on use. But I think the product is well made, nothing broken during shipment, spring is working fine, sinks to the bottom of my salt water tank easily. But it's caught lots of invertebrates and two of my smaller fish, and no mantis shrimp. But I blame the mantis shrimp and not the trap, although I wish the trap had a smaller entrance to keep out the bigger things while selectively allowing mantis shrimps in. But overall I like the trap and would buy it again. I just wish I could catch my mantis shrimp.
