I purchased the Rockwood 491 Cast Brass Automatic Door Holder and Stop in June 2019. My husband installed it and it works well. It requires a heavy push with a loud click to make it engage to hold a door but when it comes to disengaging, it works extremely easy and quite well. Note that it does require a bit of finesse on a person installing it to find this right point/height where it will engage to hold a door and disengage to let it go easily. Overall, a good product and nice in design.
