These things are very heavy!!! I wish I actually listened to recommendation of bringing a second pair of hands which is not typical at all!!! I was a little apprehensive at first wondering if they would be some cheap particle board or something very flimsy that would for sure arrive broken during transport, but seems to be very well made and I was extremely impressed with how it was packaged(as strange as it sounds) but it arrived in a wooden crate framed out to the doors perfectly and then wrapped in a cardboard box, installation was an absolute breeze and would be difficult to mess up, haven’t owned them long enough to speak to durability over time but first impressions say they will be just fine!
