Is this a remodel. I have yet to see a remodel job where flex doesn't look terrible when done. Unless you are starting new, forget it. If you want nice you're gonna run the solid pipe stuff....what's that called? Oh yeah I remember, EMT/RNC/IMC conduit...RNC if you mean business.....
Good, Fast, or Cheap : Pick two and only two. How do you compete with someone that runs around installing this flexible junk vs. installing real conduit.
Unless the box fill has be violated I don't have an issue. It doesn't look nice but I can let that slide.
Unfortunately the workmanship part is the first thing to go when trying to meet budget. It's the one thing that is fuzzy as far as code goes. How many guys still paint the plywood board behind the load panel gray? I haven't seen it done in a LONG time. It looked nice but really it served no useful purpose.
Sorry just venting a little.
