I think I have 9 EWI snakes of various forms and sizes. They all have worked great. The sheathing is a little softer than A whirlwind Medusa. I have managed to get a couple small slices in one of my snakes but nothing that a little bit of E-Tape couldn't cure. I also have the sheathing stretch and expand a bit here but I think that my 115 degree weather is the cause of that. I have put a little extra shrink tubing in places to help prevent that. My summer weather here is a lot more extreme and abusive on gear than most of you can imagine and overall I would say that the EWI stuff really holds up awesome.
I also have several patch and insert snakes from EWI and they have all been great too!
When I order XLR connectors, I order the EWI brand. They have been everybit as reliable as the Neurik connectors. The EWI 1/4" connectors are not quite as good as the Neutrik ones but I think that the issues I have have been from the plastic breaking down in the heat and breaking the threads easier.
I use a lot of EWI microphone cables and I love them. I have had a total of two EWI mic cable failures out of maybe a 100 or so cables. They are sitting in a pile with about 30 other mic cables of various other brands to be repaired.
I have been buying a ton of stuff from Audiopile for many years and will continue to do so. In fact I just received some more cases and connectors last week.
