Professional Organization, Responsive, Met Expectations
Communication is excellent. They confirmed what might be an atypical order. Carried it out, in less time than advertised. (The advertised lead time was long, but written; their actual time to deliver was much less than that.) Their website search function worked well, though they did have an error on one of their website on the pictures, but the description was correct. I pointed this out to them, and they fixed it immediately, and the correction was live on their site the next day, that is responsive (and errors happen). For people, it’s how it goes after a nit that matters, these people seem to get that and work hard and professionally to do business. I am buying again.

The Matrix team was wonderful
The Matrix team was wonderful. While the product required a long build to order time (which was a disappointment as their website stated ready to ship night), Matrix communicated status in time way. And the product was exactly what I expected and was delivered a few days ahead of schedule.
