Excellent customer service from the seller, but will return
December 16, 2016
I am amending my comment here. After leaving my original comment, the Seller (Groovy Center) contacted me. I appreciate that. I tried this tuner again, side-by--side with a Snarky tuner, on the bridge of my cello. As I was tuning, the Snarky showed that my cello was in tune, but the Real Tuner showed still "flat." This happened with each string. So, despite the excellent customer service by the Seller, I will still return the product.
