"I got this keeper two years ago, and it has made feeding my leopard gecko much easier. The tubes are very useful, because you just tap out however many crickets you want to feed your pet, and you can also easily check how many are left so you know when to buy more crickets. The door on top is also useful to pour the crickets in. I've only had problems with the tube opening covers breaking off, and the side cracking a little bit, but that was because it was accidentally dropped, and cleaning the tubes. However, it keeps the crickets in, and it comes with food/water bowls, and it is the perfect size for up to 25 crickets."
