I have bought over 12 of these units and they are well built and work well. The problem is that replacement parts are not available and it is very difficult to recode the units to match the building's master key system. I had a locksmith who broke 2 pieces because he couldn't assemble the handle properly and we lost 1 bearing in the handle. These bearings are not available, so you will have to buy a whole new system.
