Great company; good communication

Delivery was a little slow, but it got there in time for the installation. Turned out to be the wrong part. Katie was easy to work with to get an RMA number and return it.

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.
