Don’t bother poor quality components dosnt work.
Don’t bother. Lack of instructions leaves you googling to try and find any help with the product. I ordered the first one and it lit up the red LED and when you press the switch it turns off the red LED turns on the Green one. Great. But then the green one never goes out. The variable resister makes no difference to the times. I built the circuit with following the picture on the item and soldered it as you would usually do. Figuring I got a dud I ordered another one. This time both LEDs stay lit. The trigger dosnt work at all. Same wiring. Don’t waste your money. Looks like the two resistors nearest the trigger switch are dud. Tried to de solder them but one broke and I gave up. Can’t test the caps but the resistors will cause the circuit not to work.

great product, poor documentation
Product was great, but links provided for the documentation did not work

No Documentation
I bought this as a kit of parts to adapt for a home-brew project. I have experience with this type of circuit, but the documentation links on the website are dead. The only documentation is for a different model, so this would not be suitable as a training project.
