1.Safe - Selection of the best flame retardant insulation material, nylon PA66, which has long service life, no resistance to corrosion, aging, pressure of 4kV and resistance to electric shock. 2. Easy to install - compact wire connectors do not require tools. Just plug in and turn on, then finish. Instead of traditional electrical tapes and twist-type electrical connectors, technological innovations reduce wiring time by over 70%. 3.Reusable - This compact wired connector is suitable for both soft and hard wire. Each junction independent shrapnel, different wire managed separately, different diameter can be connected safely. There is a test hole in each surface of the cage, the electrical test does not require removing the tape, which is intuitive and easy. Most importantly, this is a reusable connector. 4.Widely Used - Compact wire connectors are widely applied to building wiring, for example to control multiple lights with one switch. It is ideal for compact and complex
