I admit it is heavy, but it is sturdy and safe.  It is definitely too small for a permanent home but it is great when traveling.  I break it down and carry it in a suitcase, once I arrive I easily put it back together and take her out of her travel carrier... My parrotlet acts almost as happy as she does in her larger permanent cage and now I don't have to waste money boarding her when I go out of town to visit family.  I have the nina playtop cage by the same company as her permanent home and so this is perfect as her home away from home.  I also use it to take her outside with me to sit on the patio, she stays safe and secure but still feels like a "real bird" getting to go outside.
