Perfect if you want to straight up split cables, but be cautious if hoping to add bulkier things like adaptors. I wanted to split a 3.5mm cable into a 3.5mm cable and a bluetooth audio adaptor (also purchased from PrimeCables) but the adapter was a little too bulky to also fit beside the cable without stressing it slightly. Not a huge problem for me as my equipment is relatively inexpensive and I am not so concerned with damage, but may be a concern for some (in which case you're better off going with this: https://www.primecables.ca/p-312814-cab-667-6inch-35mm-stereo-plugtwo-35mm-stereo-jack-cable-primecables. Measured the centre-to-centre space between the female connectors as 1.2 cm.

Works as advertised fine quality for the price.

Great price, works well.

Work well.

Seems a bit flimsy, it's hard to tell, but works as intended.

good adapter
