They break all the time.

In less than 3 years after replacement the big brass colored ring used to tighten the arm mount (the big ring/nut) broke again. Split in two. No, it did not overdo tightening the nut. Turned on the faucet and the whole thing came of the wall due to the water pressure. Its a nice looking arm mount, solid, except that plastic cheap feeling nut. Made in China? I’m really very disappointed in Delta. They should offer the option to buy that nut separately. I’m sure I’m not the only one dealing with this issue.
