Works well and fast delivery.
Product as described. Seems to work but I will need to verify the accuracy of the reading. Price is very competitive with other vendor BUT the packaging is unsatisfactory, There is no paper or hard box for protection. The meter, electrical adapter, USB cord, manual and CD were simply wrapped in a bubble wrap and put inside a plastic bag. While it might be sufficient since everything is in perfect condition, it still leave me pondering of paying a bit more for the product with retail box. PS If I didn't converse or require special attention from seller, I usually give store 4 out 5 stars.
