Good service, product requires some work!

The customer service was good as we got good assistance once we got hold of the support contact centre but the YOCO lite card reader is not very well made. The button sticks which resulted in lost sales.

In comparison with other card readers - apps, tutorials and other information is readily avaialbale although I would prefer to have more upfront information available when installing/working with the YOCO reader. Perhaps a small manual for reference?
