Review on Antrader Aluminum Interior Connector Alu Profile by David Skyline

I used these to build the Hypercube Evolution, they get the job done but you have to be careful when reassembling using M6 set screws and if you push them in too far the screw can move two tabs and mess up the alignment. Also, the thread was cut in the opposite direction of where the screw goes from, sometimes the set screw can't go into the hole, so you have to screw completely from the opposite direction to allow the screw to clear the thread and then insert as intended.
