I'm happy with the quick shipment. I have not used the product yet but happy to provide an update later on. I'll definitely buy from this supplier.
Works like a charm.
I recommend this product. It is a great product, and great price too!
Well made, well produced product, easy to use and read. Appreciate the thin manual which brought back memories of how to use and where to read answers
