Probably about once every 6 months I have to replace these gates I got for the doorways in my house, other than that, they are great gates for the value of the money depending on where you purchase.I do have a pretty rough toddler as well as rough children so that could be the reason for the replacing of the gates so often too! But for the money I dont mind replacing them even every 3 months! They are just the right height/width for our doorways and they do just the right of keeping the baby and toddler out of the rooms needed!
