Nn ormal elect item

feedback is in first week of purchase all 5 pieces worked small and thin wires put me off, small open wires I had to open wires further in already small length wires wires are thin. all pieces worked like a zippy first 4 steps have low load that generates humming sound, its irritating; I think, if this is applied to LEDs and not fans, this might be a great alternative usage, if you dont want all 5 for 5 different fans. it is good value for money. I could not see "QA Tested" I was worried if all do not work, as people would call electrician to replace in most of cities and metros and I would have to undo all earlier replaced pieces, to return or replace the item in case if any piece doesnt work, then I would have to to pay electrician money to remove from electric boards again, and next time again call electrician and pay. But since there is 6 months warranty, I was ok to take that risk. But I tried to test and fix on my own. and I did become electrician to do work at my home and save some money. I was wondering how to determine which wire goes where, it was unclear and very small circuit diagram, difficult to understand not very clear if you have to do yourself and doing it first time. but you will be able to make out, if you are determined to fix things on your own. It is a process that one has to go thru, if doing it first time. However from product point of view, overall I think it is value for money but can do more. 6 months warranty is good confidence. just that , add one sticker "QA Tested" label after certifying the product for selling. I saw a hologram but unsure if it is certification mark.
