One of the best things about Lutron is that you can replace colors without replacing the device. If you have a Maestro dimmer, you can order a RK-D-WH or whatever for around $10 and not have to replace an entire maestro dimmer or change the programming if it's part of a system. Same for keypads and a variety of other products. Unfortunately, the same is not available for Diva dimmers.
On top of that, Diva's paddle have a spring behind them that is held with a fragile plastic tab that breaks off overtime causing the dimmer to not be able to turn off. All it takes to fix it is a new paddle plate so instead of spending $10 on a new one, customers have to pay $30 to replace the whole dimmer when the actual dimmer is perfectly fine.
I've found myself saving old plates from damaged dimmers so I can offer that and save customers money.
