This is definitely an improvement over the design of Lee's Cricket Keeper which is prone to breaking thinner plastic parts like pipe caps but has its own design flaws. If you're holding a lot of crickets, egg crates, or other surface-increasing substrates, lift the corner of the tubes to give the "wings" some clearance over the tubes. Small to medium sized crickets can climb pipes and escape easily, I was so anxiously convinced the other day. I removed the hoses and sealed the valves from the inside. Updated 06/18/2015. I've used it this way with toilet paper rolls instead of tubes and it worked great that way. I could have saved some money and just bought a basic cage, but I would not have learned some of the important lessons of cricket husbandry!
