It's good !
Loose parts - that's why it is called and sold as a KIT

False advertising!
Buyer beware! Damn thing comes in pieces, not fully assembled as shown. Get you solder gun cuase the resistors, capacitors, lights, etc all come loose. Much assembly required! EDITORS NOTE: That is why it is called a KIT....

MK-1021 kit
Super item, I purchased 2 for the fllicker effect in two early 1900's Rail Road lanterns, I replaced the red 5mm LED's with 3mm yellow ones on leads and used orange F/Top LED's set lower then the yellow's (on leads) to cast a glow in the globes. Added a 9 v. power supply, wonderful item.

Great Kit
Just finished one of five I bought, took less than an hour to complete. I bought these to make railroad crossing signals , but am trying to figure out how to display them without the board showing?
