Installation was so easy. I did 10 units in just a couple of hours. Much more ease of operation than round knobs and the appearance is so nice with the bronze highlights. Couldn't be happier.I used this door lever knob to replace an old, non-functioning brass doorknob in my vintage mobile home. It was very easy to install, and looks great. My only issue is that now the vendor does not have any more of these door lever knobs available - I wanted to replace all my doorknobs with these lever knobs, and now they are no longer available. I can't seem to locate any of the same style anywhere else, either, so I am very frustrated. Other than that issue, I'm very happy with the one I have and it looks beautiful on the front bathroom door.Bedroom door knob in camper broke. Bought this to replace it. Fit perfect. Easy install. Would buy again!I had a doorknob that just fell apart. This one is identical to the one that died... It was so simple to install it... And within seconds my doorknob was in working order again.We were taking the “trailer” out of our mobile home and these knobs really helped with the makeover. They fit perfect and looks great! Easy to install.They are ok not high qualityVery easy to install and at a good price.Not sure how long it will last. Time will tell
