I had some set up issues initially which were my fault, not the seller's. The seller responded immediately with instructions on how to fix the problem.  Then, a couple months later, I noticed an additional problem related to my initial set up and reached out to the seller again. Once again, the response was prompt and immediately solved my problem.I can't say enough good things not just about getting a good product, exactly as it was represented, at a great price, but also the excellent customer service when I needed.  thank you!
