Used for about 3 years. The wheel joint is missing, but it's not a problem since there's a wheel stand (adjustable height). The wheel broke, so I bought a new one, and it's blue. If you want to attach it directly to the cage, please purchase separately. Contents other than the Roomy cage: ⚪︎ Bath sand (unopened) ⚪︎ About 1/3 of the bedding remaining ⚪︎ Exercise ball (runner ball) ⚪︎ Sand bath, separate cage ⚪︎ Cooling plate ⚪︎ Cooling cube ⚪︎ Panel warmer #Hamster
