Review on 💡 Screw Terminal Block, PUSU Dual Row Eurostyle Terminal Strip for Electrical DIY and Home Projects, 12mm2 Wire Gauge, 12-Position 380V 20A Terminal Block (Pack of 10) by Chris Bowden

The terminal blocks grip the wire with enough force to hold the wire securely in place. This requires the bolt to bite into it with quite a bit of pressure and the block itself to withstand that force. This product does not meet either of these requirements. First the bolts are cut so that the bolt must be driven deep into the block before the threads start to bite. This means that the available wire space is drastically reduced. Second, the screws and threaded hole in the block's strip easily prevent any pressure on the wire. Third, if you manage not to attach a screw strip, the thin and fragile construction of the block will cause it to snap in half once you apply enough pressure to keep the wire from falling out. Not only is this product absolute rubbish, it is also dangerous as there is no way of knowing how reliable your wiring will be.
