Review on 🌈 ALITOVE WS2812B LED Strip RGB Light Strip 16.4ft 150 LEDs Individually Addressable Dream Color Digital Programmable LED Tape Lighting Waterproof IP67 DC 5V for Home Bar Decor Lighting by Philip Brianne

Good: They can definitely be waterproof unless you pierce the clear rubber gasket that surrounds the LEDs. So if you need to dunk LEDs, this is for you. Inexpensive. Flexible, hasn't let me down yet. What needs improvement: Power connectors are the perfect width, but the length needs improvement. To fix this I sacrificed the LED at the top by clipping it right on the edge of the conductive connector just below 5V D0 and GND. This allowed me to use the entire length of the conductor instead of half. When I first started cutting them I had problems with cutters not doing 50/50 on the cutting line marker. Sometimes I got 80/20 which wasted one of the sides. As long as your runs are long enough, it's worth losing an LED here and there due to clipping at the top. I would pay an additional $1 to have the connector twice as long to make it easier to use "sandwich" connectors.
