Good Value and Well Designed
I build kits for recreation. This kit is a reproduction of a circuit in many audio websites. The quality of the parts is good and the circuit worked on the first try. The holes in the case are a little small to accomodate the jacks and the potentiometer so I used a step drill with an electric screwdriver to enlarge them. Using a wall wort from another headphone amp that I have, the circuit worked on the first try. The only issue that I have is that there is some power supply hum when the volume is at maximum attenuation. This goes away when the volume is turned up. I will troubleshoot this and fix it. It may be the wall wort. I am happy with the kit and plan to use it to listen to music and podcasts.

Basic Dual Microphone Reverb Module
I just received this today (28MAR2017). It did not come with any information about how to hook-up, what power to use, and specifications or schematic. On the other hand, this is a basic board with two microphone inputs and one echo chip for a reasonable price. There are more complex modules available but this suited my purposes. I haven't actually had a chance to hook it up and put sound through it, or even power it up.
My initial guesses are that it is powered by a single 5V supply that is well regulated and filtered.

Does not play mp3.
I purchased this hoping that it would play mp3. Upon reading the instructions further, I discovered that even though it says MP3 in the title, that is only the name of a mode, and it does not play mp3 files. They have to be converted to something else first. Maybe I will find another use for it. The other problem is that the socket for the TF card is coming apart. I will fix it with glue, but for my purposes I would not buy it again.
