Kit came with no instructions - had to read blurry schematic

This kit came with absolutely no instructions and the PCB was not marked with the component values. I still managed to successfully assemble this kit by reading the schematic in the Amazon product description, which was very blurry, as well as the photos to understand how to solder the resistors to the sound chip.All parts were present, with one extra of each of the SMD resistors.

Don't bother... no pcb labeling, no component list, no instructions, etc!

I don't get it... even the example shown in the photo shows a component sheet/instructions underneath, yet when the kit is mailed out, you get no such thing! Not even a link to the component list. You don't really even need instructions, but at a MINIMUM you'll need a component list because the pcb has NO labels letting you know which resistor, capacitor, etc., goes where. Ridiculous!

total junk

When it arrived it came in same bag as pair of slippers. the little tiny parts were every where not even in a bag. the ad for this junk says "5 sets" there is only 1. other reviewers noted also. Total false advertising. I am A beginner to soldering, it would take eons for me to have ability to assemble. Also no instructions at all. Amazon should be ashamed to let these schisters sell there goods on there site.

Missing parts

My kit was missing the 100 ohm resistor and the TQ9561. Fun to solder but cant test it with missing parts.
