The Home key issued to me did activate. Managed to get a TPM-less MBP onto 11 with a stopover on 10 and the help of MediaCreationTool.bat.
These are best for projects here & now. Based on prior Woot threads, buying such keys for future projects can be a gamble.
As always with this “deal,” DO NOT BUY - these are gray market keys at best.
If you do decide to risk it, only do so if you’re going to use it immediately. Even if you do use it immediately, be prepared for the likelihood that Microsoft will invalidate the key later for being an illegitimate sale.
Don’t Buy!!! It is a scam. The Product Keys don’t work. Asked for my money back and they sent me a second code which Microsoft said was not valid also. It is a waste of your money.
