This kit contains a few unneccessery stuff like Antistatic mat, gloves and even the DC power supply isn't needed here, he could use the miner's PSU, if he would open a repair shop he could probably invest in all those tools, but to simply fix your own miners and perhabs some of your friends', then my suggestion is to watch the repair videos and write down a list of the things they use.

Also if you are planning on buying the test fixture tool, I suggest you wait for a while, the latest one they have now is for the 17 series and S9/T9, and I am sure pretty soon they will make one for the 19 series, you might need that later on when you buy S19/S19pro/T19 gears, it would be cheaper to buy it once than having to buy it again when the time comes.
