My cockatiel loves this perch!  She is the most avid chewer that I've ever had in such a small package, so this perch is the ideal solution for her.  She has a manzanita perch in her "condo" that just frustrates her, since the wood is so hard she cannot break any of it off.  This perch is very hardy, but the nifty little pieces of wood that she can break off just makes her day (and it's not terribly messy, so it makes mine, too).  I don't think that I'll have to replace this one any time soon, and feel good about highly recommending it to other bird owners that want to keep their birds from getting bored (note: I don't mean to make this sound like a toy replacement, but since most birds have a relatively short attention span, they need a lot of different stimulation to avoid boredom).  You will not be disappointed if you purchase this for your feathered pals.
