Amazing sturdy wheels. But when you take it out of the box, the frame is bent and I couldn't unbend it to its proper shape. Perhaps it could be packaged with more space so it was not bent so thoroughly. Unfortunately my persian cat who has a mountain of thick fur couldnt fit comfortably in there even though it a large. Its a shame because its a good product. You probably won't do this but it would be a good idea to make an extra-large.
Prossturdy wheels that steer 360 degrees so carrier won't fall on its side like Pet Gear.
Conscarrier bent too much out of the box and couldn't be unbent sufficiently giving it the shape it was meant for.
