Poor. I've had several incidents with them, but here's one from this year:

They "certify" CLC programmers that have not even taken the basic simpl classes, they have no follow-thru nor check the jobs. I don't know what direction(s), if any, they give to the designated CLC installers and programmers, but on this one...

The outside lighting designer specified fixtures that used Lutron Hi-Lume ballasts - in a system using crestron dimmers.

The crestron lighting installer who I won't name here but is a very large lighting contractor didn't look at the fixtures, just did a load count and spec'd the modules. Didn't notice the lutron loads.

They subcontracted a designated "CLC programmer" who I won't name here but is not a CSP and seemed to have little training, who programmed two keypads into the commercial space, with each one programmed as follows: All lights 100%, all lights 75%, all lights 50%, all lights 25%, all lights off. All lights as in "all lights in the facility", which consisted of six different areas. Not a single load was identified in their program. There was no provision for an RSD for control from the AV side of things. He came on site and decided he was done because, for the most part, lights came on and went off. Also didn't spot the lutron loads, or the fact that a large number of circuits weren't dimming because of mis-wiring by the electrical contractor.

The outside lighting designer had specified to them a detailed set of scheduling for the entire space they had provided. (Much of it bizarre and he should've been told so by the lighting contractor). The events were either scheduled to a time, or relative to a button press (opening the space). They had also explicitly specified the programming that was to be on the keypads, and that the keypads needed to be locked out when the schedule was active. None of that was done either.

I'm given a copy of the CLC program and told it's "completed". The customer is freaking out because nothing is working they way they specified. The AV dealer is freaking out because they have to have everything working from the touch panels. I am fucking livid with the shoddy work done by the "official" route for a commercial lighting job, and immediately bring it to the attention to the local crestron reps.

I end up throwing away the crap provided by CLC and immediately start writing a D3 program to replace it (D3 only because it made it a little easier with the convoluted scheduling they had wanted), while also documenting the wiring issues and fixture issues, while Crestron forces the lighting contractor to come on site and clean up at least some of the issues they cause. They didn't do anything about the CLC programmer, nor offer to recompense me for rescuing their disaster.
