Update... Well its now almost a year since purchase and and no problems, ends still lock into place with a sound click, have left MTS 164 MS plugged into desk since new. The only bad point was I had removed protection off snake plug and someone moved before I had coupled it up dropping plug onto corner of a case which slightly bent a couple of pins. Luckily not too bad and have straightened them successfully so be careful to keep covers on until you can couple plugs up. Any way I still recommended all 3 products so read on for my initial review from 10/06/16....
For those who cannot afford Cat5 cables and expensive preamped stage boxes.
Purchased a sssnake M1604 30M multicore in 2007 which has given good service over the years but now one return channel has gone down so rather than fix chose renew with MTS 164 SB, MTS 164 MS and MTS 164 30M multicore.
I have to say for the price I am not disappointed.
The channel / return sockets seem to be of the same quality as the original but tighter fit being new.
The outer body seems smaller, but except for the newer paint work cannot see any lowering of standards.
The best part is the Harting style connector, (reason for choosing) possibly a Wain, but male and female ends connect with ease plus the reassuring solid click as the locking arms snap into place gives confidence.
The surprise bonus is the plastic dust cap that comes with the SB, (and also on the MTS 164 MS) just change the thin plastic loop that retains it for a stronger one.
Also comes with travel bag, but would recommend some other way to protect the channel release buttons.
So again for the price .... lets see in a years time, if it give the service of our old snake then... but at the moment 5 star.
