Review on HiLetgo® Engraver Printer Expansion Arduino by Ken Beasom

Normally I wouldn't complain about a $7 purchase because my expectations are very low. However, this product and this seller failed on all levels. Obviously the connections are hand soldered and not very good. In places, even on the tips of the pins, isolated drops of solder were still visible. When the units arrived both had a lot of wires that were horribly bent and both had whole rows of pins that weren't soldered straight so they had to be bent. One of the two shields was completely dead (the stepper motor drivers were not powered). The refund isn't worth my packaging time, but no one should ever buy this product. They also. It's clear that they care less about the product they deliver.
