Lees Kritter Keeper, X-Large Rectangle w/Lid(Assorted colors)

The lid came broken, so the window just falls right out. I got this to transport a baby beardy from place to place which I obviously wont be using this for now. Will edit review if I ever get another lid sent to me. Very upsetting. The base itself feels sturdy but the lid just felt cheap and was semi difficult to get on or off, not that it was a tight fit, just that it felt like i would be breaking the plastic lid just to get it off. Just trying to keep it honest.

Nice size, perfect for my critters. Lightweight and easy to move around. The lid is a little difficult to open.

Excellent multipurpose containers. I use to house different sizes of crickets and Dubia Roaches.

Just what I needed for my breeding needs. The size was great. I purchased many of them. Will be back in the future.

This product was just placed in a large box with no padding or protection of any sort. It arrived with 3 large cracks in the plastic and part of the top rim broken off. It was not even close to salvageable. I was very disappointed.

Ive used these for a good many years to house a wide assortment of arthropods, small juvenile herps, etc. They also make very satisfactory nursery tanks for baby fishes if you dont overstock them, and use them in an area where the temperature doesnt fluctuate too much (their limited capacity offers limited protection against temp swings even if you use a low wattage heater with a thermostat.) In a fishroom with appropriate ambient temperatures, they make fine tanks for many tropical killifishes (the annual killies that inhabit temporary rain pools), and Betta breeding and female community tanks. These are made of clear hard polystyrene plastic (except the colored polystyrene lid). This material scratches easily, and readily cracks or breaks on sufficient impact. It degrades when exposed to UV light, and (much more slowly) to sunlight or bright natural light, thus these are unsuitable for long term use with UVB or full spectrum lighting. Several people have posted questions about using these to house garden snails. Both land and aquatic snails will eventually cover the sides with scratches from their tongues (radulas) as they lick at the sides when in feeding mode. Land snails will slowly scratch the sides by dragging their shells against the plastic. I use these to house kingsnakes past the hatchling stage; they are excellent for this purpose if properly furnished. The reptile heat mats sold for use with glass bottom aquaria may get hot enough to melt or warp the plastic. I use (and recommend) the seed/cutting starter heat mats that Amazon and many others sell, to heat these. If you cover these mats with 2 layers of household aluminum foil, position a single foil layer below the mat, and keep the mat slightly raised from the supporting surface (e.g. by putting the foil covered mat, with the Kritter Keepers on top of it, inside an appropriately sized plastic storage container, with the latter raised an inch or so off the supporting table), you can safely use these within a wide range of ambient temperatures without the use of a thermostat. Just make sure the snakes have an unheated floor area to cool off in. I unplug the heat mats when daytime ambient temperatures start reaching 80 degrees F. These mats use less than 40 watts and can heat 2 to 4 X-Large Kritter Keepers (depending on average ambient temperatures) when housing kingsnakes. The extra height is also a plus for keeping snakes, as it reduces the chances that an overeager snake will bite and attempt to constrict your hand when you try to drop a thawed out feeder animal into its cage. I would consider the X-Large Kritter Keeper unsuitable for keeping the following (some of which are pictured on the products printed enclosure!) It is really too small to adequately house pet rodents, such as the Phodopus Hamsters pictured, even if they are given an exercise wheel. As many reviewers have pointed out, any rodent that can reach the lid will quickly chew through the thin grid and escape. Laboratories use clear polycarbonate plastic cages to house mice and rats, but these have sturdy metal bar tops that are designed to prevent the occupants from reaching and chewing on the edges of the plastic. This product is also unsuitable as a long term enclosure for Green Anoles and other active, skittish, basking lizards; it is too small for these nervous, very active animals, and the UVB lighting they require will make the plastic brittle. Land hermit crabs will quickly scratch the plastic. Small feeder/pet roaches, small crickets, etc. will quickly escape if they crawl/jump to the lid. If you need a secure top (as when keeping snakes) but find the difficult to remove lid to be a nuisance, try releasing and slightly raising the lid from one corner first (all of my Kritter Keepers have one corner where the lid is easier to release), then releasing the lid from the remaining corners in succession. For use as a baby fish nursery or Betta tank, position the lid in an inverted position atop the clear plastic; this will prevent small fishes from jumping out, and spare you the hassle of working the lid off each time you feed the fishes, change their water, clean their filter, etc. Would NOT recommend using the small clear plastic panel door in the colored top; the small extensions that secure it when snapped fully shut are tiny and fragile, and will quickly snap/wear off after repeated closure. Thanks to Amazon for sending these to me in Lees original individual boxes within a larger shipping box; this gives these fragile items much better protection than they would have if they were stacked together in the same box. The extra cardboard is easily recycled.

I am pretty happy on this purchase, although there was a minor chip by the lid, but hey, I used the chipped area as a hose tube feed for the airstones in my tank, other wise Im glad about purchasing, its a4 gallon and can hold my betta fish.

Kritter Keeper looks like it will do the job, but I received one with a hot pink lid rather than the blue one pictured. I absolutely hate hot pink. Thats my gripe.

Great for my feeder crickets. They cant get out and theres plenty of room for all of them. This is great!

The small cages are easy to clean, easy to carry around, and are great for holding frogs for 1-2 days. The lid is snug, so it keeps the frogs from being able to jump out.
