My keyboard is having issues with the "e" key

So, as the title says my "e" key has been giving me issues (even typing that out I had issues) where the key won't even register and I'll need to press 3 - 4 times to get it to even register. Issue: this is my second keyboard (Rma'd) which had the same issue. I'll gladly send a video link to show the issues on how bad it is. any suggestions? (I also clean my keyboard once a month sometimes two) Edit: this is also the black widow TE
