The owner of SA died in 2018, and they haven't been the same since then. The changeable faceplate was a great innovation, but I have had many failures of their switch contacts, the physical switch the button presses.
1) The first SA mistake was when they made a low-cost version to sell at Fry's Electronics, for the home "DIY" but it turned out mainly dealers bought them to save money, and they lost money on every switch. 2) Their second mistake, in my opinion, was when they didn't upgrade their firmware when the 2.0 standard was released, which mean their switches don't support a repeater. PCS wanted money for the firmware, and SA didn't want to pay it. Web Mountain, which paid for the 2.0 firmware would buy the SA switches and upgrade them. I have several and they work good.
Looks like another one bites the dust.
