Review on Cable Matters Grounded Outlet Smart Switch by Tay Fair

The Cable Matters 3 Grounding Sockets is just what I needed: 1. Reliable brand.2. Good price ($9.99).3. Red light that can be seen day and night AND front or side.4. On top; OUT is at the bottom.5. Two of these switches fit into a single standard outlet (top and bottom outlets).6. you are small There are many other similar items that do not meet one or more of my needs. Suggestions for improvement: 1. Make it a 4-pack (for $11.99) because there is room in the pack. This also prevents shifting and scratches during shipping. Provide it in both white and black.3. List it in UL.4. Make it available for use in double sockets (4 sockets per panel) with a switch left and right. Here 4 packs would be very practical. Hope they last long.
