Through the years,I have kept Gerbils,Mice,Anoles,Gecko's,etc.and I found this screen to work the best because of the door.
I can't tell you how many times a lizard has escaped when using the regular screens.Certain animals/Reptiles are very fast on their feet.I'd no sooner start to take a regular screen off and before I could finish,something was running loose!
The door stopped all escapes from happening.I would have enough room to get my hand in and out and still have the majority of the tank top covered.I would definitely recommend you to spend the extra money if you're looking for a screened top.

Pros: EFFECTIVE!

Cons: none

I like this lid for my quicker lizards like the anoles, and wall climbing geckos. It has a small locking door just the right size to reach in and change bowls or spot clean. I also use it for all my arachnids.
The only bad thing is that the screen is a large grade screen meaning its holes are a little large...so i dont recommend feeding fruit flies....even the wingless ones eventually get wings.

Pros: Small opening door

Cons: screen has larger holes...not good when you have to feed fruit flies

These lids work great. They are cheap and they stay tight. They aren't too tight or too loose, work great for all kinds of reptiles and small animals. I have lamps setting on top of them, and they are resistant to the heat, and yet let plenty in and not hold too much.

Pros: Work great, cheap

Cons: none
