any money saved on priced you give back in labor and then some.
PROS: they worked for the application. the shell is really strong and seems durable, the price is right for a double unit.
CONS: not easy to use. slowed the install process down. wasn't a big deal till we did 210 of them. then it added hours to the process. Also the fail rate on initial install test was much higher than the keystone units. Had to trouble shoot alot more and correct during testing and labeling. will stick with keystone jack and double spaced box next time.
