Been converting all house lights to LED and decided to add dimmers to several rooms. Made sure to use dimmable LED bulbs. Tried several dimmer manufacturers and models with mixed and frustrating results - many seemed to cause the dreaded LED flickering and/or, once "optimized" to minimize flicker (internal adjuster screw), did dot provide much dimming range. After a lot of trial and error these Lutron AYCL-153P units are the only ones that worked consistently with good range and no flicker regardless of location and light fitting.
It is important to follow the wiring instructions which come with the product to ensure the switch functions properly. Otherwise the product works well and was delivered on schedule.
