A good value product
I bought this for a project at good value, simple to assemble but would have been better if the assembly instructions came with it rather than having to search online for them...

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.

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.

Okay
Just about okay.

No instructions included, online documentation does not match the product
No instructions included, parts do not match the board, online documentation does not match the product. I eventually worked out how to get the product working but then it failed after a few minutes.

No instructions and ones on website don't tie up with the actual board
