2 Hamster Tube Kits, DIY Hamster Tunnel Adventure with External Pipe, Transparent Connection Track for Rat, Mouse & Small Animal Sports, Expand Cage Space

Excellent value for the amount of pieces it comes with! Beware, though, although these look like it in the pictures, they are NOT the same diameter as the other more expensive and colorful Kaytee Crittertrail tunnels/tubes/accessories. Therefore if you’re looking to expand your Kaytee enclosures, get their branded parts OR expect to do some minimal DIY (these pieces are a bit larger so their rings are too big for Kaytee tubes and Kaytee locking rings do not fit these, so you’ll have to use the slighly larger rings and glue them onto the Kaytee ones) All in all it worked because I was making my son a custom enclosure using a 116QT plastic bin after deciding our store bought one was way too small for our hamster. Just ordered a second set to continue to expand and provide entertainment for the hamster!

These are not very well made. The tubes work, but the attachment to the cage does not want to stay on. So this tube keeps falling off. You receive two tube sets. The May be combined but are designed to be two separate tubes that connect to the cage. It is hard to attach them. I feel as though this was a horrible purchase. I bought another item to attach to the cage and it attaches well and sturdy.

I returned item mainly because it would not work with the cage we have. The pieces felt like they would break easily and not as easy as I thought it would be to connect.

Excellent! Robo approved 🐹 some parts a bit stiff to put together but def manageable.

Very cheap plastic, but looks like it will work. We will see how long it lasts

Disappointed. The elbow tubes easily break in half length-wise while trying to connect them together or to the cage’s hole. Material seems cheap. Lengths don’t match up to form an outer path on a 22-inch wide cage. They’re either too short to make it around the second corner, or with an extra piece, it’s too long to line up with the other hole.

I love these blue tubes. I got them to work with the tiny Tails tubes that came with my forts and I even added KT tubes by switching out the Rings.

This tubing will not fit with existing kaytee tubing and it doesn't stay together at all. I can't even see where there are notches or clips to hold these pieces together except for the rubber ring, which is very loose and will in no way hold up to anyone bumping into it, let alone an animal using it. Infuriatingly frustrating to put together because it falls apart every time you touch the tubing next to it. Super cheap and thin plastic, very bad quality. Don't get this if you're actually using it for an enclosure.

Went together just fine. No issues. I glued them into my chinese dwarf hamsters cage so he has another way to get to the next level.

Un peu compliquer à installer. Sa ne semble pas fonctionner avec tout les modèle de cage mais j'y suis parvenu quand même. Mes souris en son super satisfaite !

Cheap brittle plastic tubes with a joining system you have to brute force to get together. The adapters the kits come with seem to be for an entirely different tube system as they do not fit in any way.

Won't connect to existing tunnels.

Very difficult to assemble. Cheap made.
