WishLotusHamster Tubes with 2 Pipe Connection Plates, Adventure External Pipe Set Creative Transparent DIY Connection Tunnel Track to Expand Space Hamster Cage Accessories Hamster Toys (Blue)

We couldn’t use a single part because not only did the blue opening pieces not fit my standard sized cage openings, but every time we went to put two tubes together, they would both split in half down the middle! Every.single.piece.BROKE. Not buying again. It was a Christmas present so we missed the return window.

Next time I'll spend more for a better product

I use these to connect my budgies cages to each other. Works great and they love being able to go from one cage to the other when ever they want.

Fell apart real easy

it works good just be carful or you will brake the tube. it is perfect for syrian hamsters since they are bigger

I think these may be for hamsters bigger than ours (Russian dwarf). She had a hard time going up, and slid down. We got a different brand and it was better for her. Plus, these tubes are bigger than the other ones. So, we just duct taped the two type of tunnels together. It doesn't look great, but it works. We only use the pink tubes not going up or down.

Very thin and the sections do not stay together well. I’ll have to replace these with something better.

Perfect for my winter white hamster!

Had a bit of a hiccup with missing pieces but the customer service was phenomenal and promptly fixed it .. everything in package is awesome with great quality and the gerbils have never been happier with their tubes

I thought I could use it for the cage we have purchased, but unfortunately it did not work and we have to throw it away.

fits on most cages, my Hamster loves this, has so much fun in it
