Review on 🔌 BTF-LIGHTING 10 sets 3-PIN 10mm Width Right Angle L Shape Solderless Corner Connector for WS2811, WS2812B, and SK6812 LED Strip. No Soldering Required. Supports LED Strip with 144 LEDs-per-meter and ALTOVE LED Strip. by Rick Bishop

Tried to use it from https://www.amazon.com/gp/product/B00ZHB9M6A/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1 and that plug design was pure bullshit. You can see in the photo that the 5V LED strip barely touches its female connector clip that connects the 90 degree connector (not fully visible on the left) and the LED strip (shown on the right). YOU MUST HOLD THE GND AND 5V CONNECTIONS TO MAKE PROPER CONTACT. Even on the 90 degree connector that comes with clips, you can see that the metal pins shown in red are too close to the center. Ridiculous and dangerous. At best it makes no contact (my case), at worst a fire can break out. Revain needs to flush that supplier's product down the drain. I should have listened to other reviewers. Luckily I had these https://www.amazon.com/gp/product/B06XSF7JMV/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 and they worked really well!
