The product works but I won't say it was the winner of the game. Why? THE POT IS THE BIGGEST PROBLEM! You must use one that is easily adjustable. I'm just lucky because I have a jewelry set that contains all sorts of fancy precision instruments. With one of the devices, the pot was worn out after a few turns and the product went down. I removed the potentiometer and tried using a 10k resistor and then a 1k resistor but by then it was probably dead. The other two modules still have a potentiometer but with intermittent operation. Now I have 1 out of 4 that still work and I have little faith in them. In the end I ordered another kit just because my project was already developed around this module and I don't have much time. It would be nice to have a higher power module without the crazy jump of say 25 watts. As expected, there are NO documents about it. The vague description on Amazon is not a substitute for correct technical information. Nice try, but you all still have a lot to do! I would not object to the purchase; However, I would say that you may have (serious) problems with this pot.
